Hello!
With a hue i mean either that you how can i explain this.... for an example change the colour of the entire sprite or a sort of sheen over it? While with transparency I mean an opacity change, since it doesn't seem to work with gimp and only some online tools.
Yeah i noticed that part, but they just don't look child like in the facesets. you can get around it to a degree, but some more support for that would be cool.
Wish you a good day.
