I am trying to do a little bit of a design on a little program for android. I am using OpenGL ES1 for this. I am drawing 2 quads on the screen. When the quads intersects the must show a third color.

Like this:

So I am trying to mix these 2 textures into a third color when they intersect. Is there somewhere I can setup Opengl to do that?

Take a look at the stencil buffer. It can do this efficiently. – ClayMontgomery Feb 12 '14 at 16:47
