#Niko is a pretty good canvas with which to illustrate the 'cyan shadows', in i.e. renaissance paintings. When the sun is low, and under the right cloud conditions, the shadows can be blue - and I learned from an art prof that cyan shadows are an important part of the color theory of the time.
OR I dreamt/hallucinated that information
I never took a painting course, but it seems true!
@LikeItOrLumpIt I'll take 'truthy'
