Hmm. Well, just for your information then, here's your current palette:
Those are all the distinct colors GraphicsGale picked up. Although you do have a point that the SNK sprite does use 5 colors, I admit Ken is not the best example for color control. Ken has 3 major colors in his scheme: Red, Yellow, Skin. Yours has more: Green, Black, Gold, White, Skin and two misc. colors (blue/red). In addition, you're giving the green the same amount of shades as the black, even though the green color is limited to the hair. If you look at the Ken sprite, you'll notice that his hair is about 3 shades instead of the usual 5.
