NES Pallete Accuracy?

[Gors]

I understand where you're coming from, but when ripping, you got to be as accurate as possible, given the tools you have. If your tools change the color millimetrically, then I think it's still passable, despite being innacurate. The sprite will still serve its purpose and no matter how the colors change, the 8x8 3 colors + alpha transparency will still apply.
