On the piramid, it was my first experiment trying to see what came out of mixing colors in graphics gale (a specific task which is a bit of a pain to do, specially with mixing multiple shadings of multiple colors, which is needed to do lighting effects) and my ability to render lighting on objects with those colors. The grey was purposeful, chosen as a neutral color, and the strong saturated blue light too, to see the difference between colors of opposite properties. Didn't come out exactly as i planned, next time it'll be closer to that. Just a quick exercise thing.
