use shader! you'll have to make your own shader, but adjusting color saturation is quite easy. see gem documentation/10.glsl/01.simple_texture

hi roman & me are working on an videoinstallation using gem - only an additional [pix_contrast] in the gem chain hits the processing limit of our computer - is there a way to adjust color saturation in the gpu instead of the cpu in Gem? thanks&greets olsen
