<br>
</span>I guess you mean if it's possible to change the saturation using a<br>
shader ? (correct me if I got it wrong). At the moment, there is no<br>
equivalent of videobalance in the open gl elements. This is probably<br>
something soon to happen. This is clearly something doable with a<br>
fragment shader. You can experiment (or even implement your own) using<br>
glshader element.<br>
