Thanks for reading!
A question is have is did you have and specific palette that you were sticking to during your design? Or do you just pick whatever colors look best?
Originally I wanted to have the 5 colors in the game (red, blue, green, yellow and gray) be reflected in the fairies, the toads and the level contraptions. I tried to stick to that for a while, but some fairies like merry needing a different color and the brave fairy looking subpar with yellow, so I bend the rule but still kept is as a loose guideline. By the end I just experimented with colors to see which ones meshed well together.
One thing that I did manage to keep constant was using yellow as a highlight for all fairies.
