On the color palette, its easier for me to see that 32 bits color looks smooth with the color gradiation than 16 bits gradiation. I do notice color banding on 16 bits color, but was surprise on 32 bits, i also see what also looks like color banding too, but it was definately smoother. I believe its not 32 bits fault that i still see color banding, its just that it was design that way for the palette.
