Hi! I'm new to ripping sprites, and have made a mistake. 
I recorded and ripped an entire game, but since my recording was a little fuzzy, there are lots of "ghost" colors that I need to get rid of.
Please look closely at the visual demonstration of the issue. I increased the contrast so it's easier to see the problem, but you still might need to zoom in.
Is there a way, in any program, to specify an allowed palette of colors and automatically reduce the color depth of an image to that palette?
I currently use Paint.net but I'll download whatever I need to.
Full sheet attached if anyone wants to give it a try.
Please help
