Orange is fun...(avoids a Villain cliche or two)....purple and green both work and are solid genre choices.
I like orange, it is different and seems bold
Could he start orange and become redder when angry?...or be green and become purple?
I like this idea Alan, thanks. :)
I like the orange
These are all really cool, the green feels strong to me but I like the idea of the colours changing so the orange and red is also a nice combination
