These are very nice but they won't work correctly in game. The palette has to be fixed on all of them. what ever color is in the last two indexed slots in the palette will be transparent in the game and you will see the magenta through the image where ever the colors in the last two indexes appear in the image.Thats why the last two should always be set to magenta 255,0,255and green 0,255,0 most images will never use those two colors anyway.It's not really the color that matters you can use any color in the last two indexes as long as it doesn't appear in the image anywhere.
