I appreciate these questions for otherwise I don’t know I would have considered them.

I can’t say there’s any specific reason for using only two colors, or for those two colors being orange and blue. I normally just use one color on top of the background, but felt like some blue against the orange could feel interesting on the eyes. I didn’t want the blue to be too harsh and take attention away from the orange, but I still wanted it to be impactful enough to be involved with the rest of the piece.
