I will expand from a previous post on recolouring tessellations, for aesthetic purposes or simply to be able to identify the characters in these nested shapes. There are many methods, some systems just make it a mess of colours, others offer clarity. It seems that the task of viewing tessellations is beyond the 60 second limit of most people. Wander and wonder followed by head tilt is what I strive for!
Could be an interesting treatment option, in order not to stress your eyeballs!
