You can decrease the number of steps (from 1.0/255.0 to 1.0/31.0, AKA dithering) but you can't increase the number of the steps (from 1.0/31.0 to 1.0/255.0) without some interpolation. In other words: you can decrease color depth but you cannot increase it.
I hope that my Engrish (for Hushypushy) is comprehensible.

thanks. luckily i'm a programmer but am not too up to snuff with color implementation. a shader couldn't do it but i suppose them dudes that do the other type of plugins have it in their area. i'll bother them about it.
