Actually, I'm using Firefox too, and there's no problem. It should work if you have the latest version.

Hmm. I'll look into it tomorrow.

I reduced the amount of colors, but for now I've only used colors from the original sprite. I'm not quite happy with them, so I will try to experiment more in cyans and others as suggested. Added an animation to convey that he's in a running stance, and not standing still on both legs. I did not intent him to hold his sword out like that when standing still even though it looks like that might work as well. Please say what's better, and what's worse.

How was your process of picking those colors? They match up really well, but when I look closer on the sprite, the colors doesn't really look like they should work well together. It leads me to think you know something that I just can't see. (please don't just say color theory) For example the cape consists of 3 colors. Red, and orange and a brown. They have almost the same hue, are scaled in lightness, but you have desaturated the brown a lot while kept the saturation on the red and orange high. Why not keep the saturation the same? Is there any rule you follow, or did you just pick them cause they looked right?

Sorry if these are too many questions. I've just never really gotten a grasp on how to pick good colors, and never seem to be able to do it right.
