Both waterc and waterd are always greyscale for me, strip must be inadvertantly applying a custom color table. I've found I get the best results by using only 3 colors, 0,0,0 130,130,130 & 255,255,255, Using more colors adds little or nothing to the look of the water and it caused the size of the res output file to jump from 8 megs to over 50 megs.
