How exactly can I do that?

I am at my wits end. I've been searching all around the net for information about this and have ended up in this forum. I'm currently ripping sprites for a game called Crossed Swords II and some of those sprites end up getting shrunk in game. I figured there was not much I could do until I discovered the Sprite Viewer option. However, even though all the sprites are shown and I can scroll through all of them, I can't change the colors. I tried every button and every combination I could think of but I can't change the color palette at all. Is there no way to change the colors of the Sprite Viewer?
