I couldn't believe how complicated it was to make black the first couple of times and should of thank twice on how much i used it through out piece (note to self use black way less). But overall i enjoyed the idea of this unit, especially with the understanding of subtractive and additive color and taking the color wheel and interpreting it through alternative systems or visual. i think the most interesting thing Ive taken from this unit would be additive color, the comprehension of light has furthered my thoughts on future projects and piece and how i can incorporate them much more.
