Is there a way for drawing only the red/green/blue channel of a Texture?

the standard way to do that these days is with a fragment shader. In this case its very easy.

Use glColorMask(boolean r, boolean g, boolean b, boolean a);?

I don't really know what you want to do but there is glColorMask().
Even so, the best way may be shader.

Glad to help. I think it will disable drawing to the other channels COMPLETELY, meaning that you won't get the other channels updated at all, but I'm not sure. You can also just use glColor, as its color is multiplied by the texture color.
