How to overwrite color like mspaint?
I am making a painting Project using a render target.
But Color Combined. I do not want to mix colors.
I don`t need Magenta, Cyan Color. just need original color like mspaint.

I modified one of my old projects to show a method of how do that. I erases the previous color by drawing a negative value into the render target. In the material of the brush it has to be set to allow negative emissive values. https://youtu.be/4N0bo4WqJu4
there's a bit of a delay sometimes as the colors switch, I think the value in the render target sometimes gets higher than 1 so it takes longer to erase.
