So these pictures are in reverse order to show you the thought process I was trying (with varying degrees of success) to use here.This is the color "sketch" I did in photoshop.
So, I finally decided that the crab should be about the structure, not so much the paint job - I mean it's a sculpture, not a painting. Therefore, I decided to just make it a flat color. I really loved the crab when it was just gray, so I figured I could capture some of that same feeling, if it was a solid color...however, I'm still not completely convinced this is the right color ( I think I want something a little less brilliant).
This is what you call trying to create a 'gradient' of light to dark. Unfortunately, it looks more like the sky than a crab :)
I ran out of my first red, so I ended up using three different hues to complete the paint job...not with a large degree of success, however.
After completing the primer coat, I painted the entire crab black. I did this because I like having a deep rich color to build my lighter hues upon - it gives the paint a stronger sense of depth.
...I think I can take him!
