This one is for all the process junkies out there. Here are images of each step in the coloring process I used on the Star Trek/Green Lantern #5 cover I colored awhile back. The line art is by David Williams.
First here’s the original line art as I received it.
Here’s the adjusted line art with the blue lines removed. (Click the image to see how that was done)
Flat colors, using local colors.
I added a 40% color fill to help unify the flat colors and a few multiply fills to the foreground elements to begin creating some depth.
Here’s how it looked after the rendering stage. I used multiple layers set to a linear dodge to add the green highlights, and a few with some blue reflected light to help set off the figures.
Here’s the final image with the special effects added. The glow around Green Lantern and his power ring shield was done with the polygon tool with a little bit of feathering. I also used various custom fractal brushes to create some “energy wisps” coming off the shield (cause it looks cool). The swirls in the shield itself was done by sampling a photo of a bubble.
