Do you want to do something like add more red to an image?  pix_gain will multiply each channel (R G B or Y U V) by a coefficient and pix_offset will add to the channel.  You can also try the colorRGB object to modulate the color value in hardware, but the coefficients are limited to 0..1.

Hi,<br><br>Its been a little while since I am trying to _add_ a color to a pix. Is<br>there a way to do so ? The thing is that if I put a colored rectangle<br>over a pix_textured reactangle, it kind of desaturate the picture.
<br><br>I know such a thing is much easy in Gridflow, but I got to use Gem on<br>OSX for this time again. If it is the only, though, I might try to<br>compile Gridflow with its new export_pix and import_pix on OSX...<br><br>
