you'll have to make your own shader, but adjusting color saturation is quite
easy.
see gem documentation/10.glsl/01.simple_texture
it doesn't seem to work on my box. no matter, what shader i load, the
texture looks the same.
hello,
i don't understand everything on your mail.
with color = color * 0.1 , then every color component (R, G and B) will be 10
times smaller than the original texture color, so the images will be darker.
color value are between 0 and 1, so you can try curve like this :

having saturation processed on the gpu
would save oli's and my project.
I updated the svn in order to add brightness and contrast in the 1st example.
hope it will help

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

thanks for this hint - though it's my first time using shader - i
tweaked around a bit with the example. i changed color saturation
towards muchocolore in the texture.frag file. although removing color to
get a black white image i'm also loosing opacity f.e. with color =
color*
