Primary Colors: RGB vs CMYK

Primary Colors: RGB vs CMYK

Red, Green, and Blue are the Primary Colors. They are the “irredicible components” of white light. All other colors are simply combinations of Red, Green and Blue.

Cyan, Magenta, and Yellow are “Complements” to Red, Green, and Blue. You’ll note that they lie opposite the Primary Colors on our Color Wheel:

Color WheelThe reasons for this are remarkably simple and easy to comprehend!

Red, Green, and Blue, being parts of White Light, are “additive.” This means that as you add brightness to them, they approach White.

Red Green Blue

In the above graphic, Red, Green, and Blue are added to each other (using the Linear Dodge Blending Mode, just in case you’re in to that sort of thing). You can see that where they all intersect our result is White. Where only two of the Primary Colors intersect is their Complement: Red and Blue produce Magenta, Red and Green produce Yellow, and Green and Blue produce Cyan.

The Complementary Colors, Cyan, Magenta, and Yellow, are “subtractive.” As you add them to each other, you approach Black (the absence of Light, therefore, the absence of Color).

Cyan Magenta Yellow

This is most useful in the printing disciplines. We use inks to absorb light (subtracting it), and the residual reflected light is what you see as the print! The science beneath the matter far exceeds an introductory tutorial, but it is important to understand that C, M and Y are subtractive and are not Primary Colors.

Note: In this case, I used the Linear Burn Blending Mode to demonstrate the subtractive effect.

You may be wondering why the “K” (for Black) in CMY if they add up to Black in the first place? The reason is that inks-both the dyes or pigments used for color and the solutions used to suspend the dyes or inks (the “vehicles”) are imperfect. If you just add amounts of C, M and Y ink together in the real world you won’t end up with black, you’ll end up with a very runny dark brown mess. It’s also very inefficient to use large amounts of ink on print media.

Black ink solves a number of problems associated with producing dark tones with subtractive color.

Dogs, Vomit, and Cheap Chinese Food

Today. I did something very stupid. Which I would like to share.

I love Chinese food, alot. Whenever possible I will drag my girlfriend/friends/family to Chinese restaurants, I just love it!


There is a Chinese restaurant near to my office, which does a 2 course lunch for just £5, an absolute bargain. I had been there quite a number of times, and every time I came away feeling disappointed. So, a couple of months back I decided that I needed to stop wasting my time and my money going there because the food there is rubbish! It doesn’t taste good at all, and I always wish that I had gone for something different.

Then today, I felt the urge for Chinese, and besides that, my boss was going to the usual cafe that I go to, so I needed to find something different. I proceeded to hang around outside the aforementioned Chinese restaurant for about 10 mins, thinking “shall I, shant I”. I could taste Chinese food in my mouth. It was so appealing. And it was a bargain at 5 pounds. I went in, sat down, and ordered dishes that, surely, they couldn’t possibly get wrong.

I remember school dinners tasting better than what I ate at lunchtime today. I left half of my lunch, the waitress came over and said “is the food ok?” and my response…”Yes, very nice thank you”.

My nose is now 2 inches bigger than it was this morning, and I can’t get Proverbs 26:11 out of my head.

“As a dog returns to his vomit, so a fool returns to his folly.” – Proverbs 26:11

This has made me think. Surely I do this kind of thing all the time in other areas of my life.

What is your folly?

Call for musicians: “Portraits of a King”

A couple of months ago, at a time when I was feeling as if I was walking through spiritual bog, I opened the book of John and began to read it with my girlfriend Robyn. We had only intended to read a little, but ended up sitting there in stunned silence broken only by a “wow!” or “Jesus did that?!” while we read the book cover-to-cover in two sittings. The majestic and truth-saturated gospel of John reawakened my love for the Lord Jesus and reminded me why I was a Christian. Although not the main point of this post, I would advise anyone feeling cold in their faith to do the same!

A fragment of the Gospel of John

Shortly after this experience, I decided that I wanted to share the portrait of Jesus that John paints through a collection of songs called “Portraits of a King”. Now this is where some of you come in. I am looking for people who are willing to prayerfully and carefully write a song based on a passage from John. For example, I am beginning to write a song on John 11 – the resurrection of Lazarus and Jesus’ proclamation “I am the resurrection and the life. He who believes in me will live, even though he dies; and whoever lives and believes in me will never die. Do you believe this?”. I am not yet sure what style this song will be. I hope the collection will be a mix of rock, acoustic, hip-hop, jazz, soul, classical, poetry, and anything else that might come up.

The purpose of this song collection will be twofold. Firstly, as an encouragement and exhortation to followers of Jesus to look at him more closely, follow him obediently and love him more dearly. Secondly, I hope that it (at least in part) might be a powerful tool of showing Jesus to non-believers who might not otherwise here about Jesus’ life. I believe that so many of people’s objections to Christianity are simply because they believe it to be centred around a set of rules, when in fact it is centred around a real person: Jesus Christ. With this twofold purpose in mind, those who wish to be involved will have around a month to compose and record a song, which we can then put up on the internet for free download or distribute by CD (probably both).

If you are a musician and this stirs your heart then I would love to hear from you. This song collection may well end up being low in quantity, but so long as it is full of Jesus then I do not mind! If you do commit to this, then it is not a matter of writing a song off the top of your head, but you will need to prayerfully read through the scripture you are writing on, and with a mindset of reverence and faithfulness to the Bible, begin to write. Don’t worry if you have little experience of Bible study or songwriting – all who love Jesus and are willing to put in time to getting into the scripture are warmly welcomed to get involved. Get in touch with me at if you want to join in or have any questions. Hope to hear from some of you soon!

For His glory,

From the maker of the Manga bible, comes a new manga series based on the life and works of Jesus!

It is very difficult to find Christian comic books, even harder to find ones which are actually of any substance or of high standard. As a dedicated follower of the comic industry I am continuously disappointed, not by the lack of Christian comics, but by the poor quality in script and artwork that current Christian Comics are known by.

It was, with some excitement, that I stumbled across the Manga Jesus. Siku [the writer and artist], is a known comic book artist, I have seen some of the work he has produced for 2000AD and its very good. When he produced the Manga Bible, which has become very popular, I wondered if it was going to be just another poor attempt to bring comics into the Christian market, It wasn’t!

The first time I met Siku was at the Bristol International Comic Expo in 2007 [then later at the Christian Rescource exhibition in Esher the same year]. To see him promoting his work at a national Convention filled me, not only with great hope, but awe as well. Here is someone who has brought his passion for Jesus and comics together to form a great tool for evangelism and enjoyment.

This latest venture, the Manga Jesus is absolutely superb and I recommend everyone buy a copy, not just for personal use [as I have], but also as something that can be given away to others who do not know Christ and maybe want to get to know him more! Not to take away from the word of God, but as a way to lead those of a visual nature into the word, and better understand the God we serve.

Cloning Jesus

I am a huge fan of fantasy, so when I saw Frank Wu’s art work I was immediatly interested in what he produced and had to say about christians working in the fantasy media. The following text is part of an interview that Frank gave to Artist Interviews magazine and really highlights his passion for Jesus and the work that he produces:

“I am a Christian. Sometimes this is a problem in a field where a lot of the writers and editors – and fans – are atheists. Sometimes. Not always. I don’t preach, I don’t harp on people’s lifestyle choices. I don’t pick fights or judge people. They are my friends, and I try to work with them and be their friends. Are we not put on this planet to love each other?

One of the weird things about doing commissioned art is that you accept the commission before you read the story. An editor asks if I have time to do an illo for an upcoming issue. I say yes. Then he sends me the story. I hate turning down commissions, because book and magazine illustration is sometime I’ve dreamt of my whole life. But sometimes I get stories that make me tingle, and not in a good way.

“Cloning Jesus” was weird, because it was about the attempt to clone Jesus from chips of blood in the Shroud of Turin (we assume for the story’s sake that the Shroud is authentic). It would have been an interested conceit, if a similar idea hadn’t been done in a Star Trek episode years ago. Anyway… This is the only piece of art I’ve ever gotten hate mail for. I think the letter-writer was offended by the whole idea. It was sacrilege. Part of the problem I think is that people don’t really go deep enough into the theology. Who was Jesus? He was God, who put on human form and came to earth. So He was fully God and fully human. Human in that He had blood and ate food and it must have really hurt when they put the nails in His hands. Why did He come to earth? Well, partially to tell us that we should love God and love our neighbor. But also, and most importantly, He came to earth specifically to die on the cross, a sacrifice for our sins, a payment for our transgressions. For we have all sinned and fallen short of the glory of God. His sacrifice meant that we did not need to be sacrificed ourselves. Our sin no longer separated us from God, and we were forgiven. Jesus took our place on the cross. But Jesus only had to pay that price once.

So what would be the point of forcing a second coming of Jesus by cloning Him? So He could die on the cross a second time? That doesn’t seem necessary. So He could announce the end of the world and bring down the new heaven and the new earth, because the old ones were used up? Seems premature, not quite God’s timing yet. I think the writer’s point is that the world is a less than perfect and peaceful place. But rather than having God see the wickedness and destroy the world, as He did with a flood so long ago, perhaps there might be a more pleasant alternative. Maybe if Jesus could return, we would hear the message “Love God and Love Your Neighbor As Yourself”. And maybe we would do this, and the world would be a better place. For me and you. If we put a little love in our hearts.

And I think that’s what the story is about. And that’s not a bad message.”

Creation, God’s invisible qualities and the arts: Part 1

I’d like to start a series of articles based on God revealing His character through creation, and what this means for us and anything we create ourselves. When I talk about creation, this is including what is thought of as “nature” – flowers, animals, mountains, cells and so on, but also more abstract parts of creation: friendship, romance, beauty and the like. We begin with this verse:

“For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that men are without excuse. ” – Romans 1:20

Now, to make sure we get what this verse is really saying, it is in the wider context of Paul’s argument that mankind is without excuse for glorifying God and that  “what may be known about God is plain to them, because God has made it plain to them” (verse 19). This lack of honouring God, and the outworking of it is how Paul explains sin.

But does this line of argument still hold ground today? With evolutionary biology seeking to explain physical creation, and psychology and sociology seeking to explain metaphysical creation (such as love, belief and friendship), is it still reasonable to say that God’s character is plain to the modern man or woman simply through His creation? Or has creation become simply something we steer clear of because we as Christians don’t really know what we think and feel unqualified to comment?

There are two things in the last 2000 years (since Paul wrote this) that have not changed:

– God’s character (or as Paul says, His “eternal power and divine nature”)
– Creation (not to any significant degree, anyway)

And so the only thing that has changed is people’s perceptions of where the two meet. This is where we as Christian artists, musicians, writers and other creative people come in. We have a massive opportunity to ask God “Teach me truths about Your character through creation”. As we begin to see these truths in creation around us (and remember, this can be either things within nature or things like friendship), we can then express these links in our art, our music, our writing, our own creativity. In this way we begin to connect what people see, feel and live in their day-to-day lives with the truths of God’s character that underlie what they experience. It is as if God has left little witnesses about Himself, imprinted in all that He has created, and He now invites us to point out the meaning of these images through the things that we create.

This is an exciting opportunity that deserves thought and consideration. In my next article we will consider how this could be put into practice in what we can learn about God through creation in nature. Let me leave you for now in amazement of the complexity of life with the photo below. It is a microscopic photo of an immune cell destroying a bacterium – it boggles the mind to think that thousands upon thousands of these events happen in your body every day to keep you alive, while most of us never even know this is occurring. Let us open our eyes to the the complexity and beauty of nature around us, ask what it teaches about God, and express these links in our own works of creativity.
