Any idea what shader or any other method in openGL land I can use to turn a white circle to yellow?

turn-white-to-yellowish-with-a-shader

Sorry if this is too obvious to be useful, but how about the object's 'color' attribute?

You want something more than just changing the @color attribute to "1 1 0 1" for [jit.gl.gridshape @shape circle]? Does it need to function so that if the color happens to be white, it gets changed to yellow, otherwise keep the original color?

this would be the solution if the answer was "yes" to the second question.

It seems I need to change the color in a texture. Any ideas how I can do that? jit.gen does not work there.

Nor any possibility to change the colors. Or I didn't find it

check out jit.gl.pix. using your patch, it'd be something like this:

you can also create geometry inside gen objects, so you can have objects created by vectors.

your final intentions still aren't very clear, but hopefully this will guide you.

My intentions are to create a white round mask that would function as a mask as well as the color for it. And that I could change the color of it.
