I decided to give sprite editing a try, and I must say, I’m quite pleased with the results! I should note that most of the coloured bits on the dress used both methods you described in the tutorial, since I found that a colour layer on top of a colour overlay made the colours gorgeously bright. The exceptions are blue and purple, since blue colour layer did nothing but colour the lines and purple made it look more like pink.

oh, this is lovely! you’re right; the color overlay really helps make it pop, especially with a fairly muted palate like azura’s. although I wonder if you could fix the purple overlay problem by using a bluer purple?
