Using block colours based from Merry Structure I have done a little dark to light chart. With this I think the character should be more along the darker side due to I feel it would fade and blur with the background.
Using some earthly colour tones I have played with some patterns. I think to much pattern takes it away from the world, however, number 15 to me looks like has something going on. I still quite like the idea of a dark character but I do like the faded colours blending.
