I am looking into changing the color palette of my game. I was told that my game has too many colors, and also I think the palette I've used doesn't really look that great. The problem is now I have hundreds of sprites and I can't go back and redraw every single sprite. So is there a way to automatically update sprites to a new color palette? Is there software that will do this for me?
If so, what recommendations do you have? Thanks! Here is an image below of what my current graphics look like to show what I mean:
