Cover illustration for Nobrow7 (from its website)
it looks like it uses more than 4 colors, but it is because some colors are overlapped with different saturations. For example, you can make green if you overlap yellow and blue.
I chose Fight Club. I don't really want to describe the movie, but it is about terrorism, identity, capitalism, and finding ego. You need to watch the movie to understand what I am saying. So, I did several sketches.
So I did, and I liked 4th and 5th. I liked 5th one more, but because I had too much portrait works in my portfolio (I still have many portraits), so I decided to do 4th one.
Here are my 4 layers of yellow, blue, red, and black
And when I put all the layers in multiply option,
it becomes like this. If you are really bored, you can try to save the 4 images, and multiply them. It will be exactly same and the last image.
