I wrote a short blog post about the painting process of the Chaos Toad. I used exclusively Kimera colours for this one, just to take them for a spin.
My overall goal was to really push the contrast. This can be done with lighter and darker areas, but also with warm and cold colours (as in the two skin tones) and via saturation.

The skintone is Pthalo green with some Cold Yellow mixed in and Red Oxide for the shadows (green and red can be used to make a chromatic black). The lighter skin sections are a Warm Yellow with Red Oxide for the darker areas.
Two other areas that I wanted to add some interest to, were the loin-cloth and the chaos projectile. The loin-cloth was painted using a Phtalo Blue Green Shade to work with the main skin tone, while contrasting with the warmer yellow skin. This time I darkened the blue mixing some Phtalo Green in it as well as some Carbon Black. Highlights were done with a bit of white mixed in. A subtle texture provided even more contrast to the surrounding sections.
The chaos projectile is going from a Carbon Black with a bit of Violet mixed in to Magenta and up to pure Titanium White.
