Thanks a lot, that blend example helped. The shader is also very interesting, haven't really looked too much into shaders yet. Stencil seems to do the job for me at the moment (aliasing isn't an issue right now) but I'll experiment a bit. Thanks again!

Thank you! Stencil looks exactly like what I want.

Yeah, I think I confused myself too. Sorry. Basically, I want to combine two images/canvases. One is monochrome black and white, and the other is a background that "tints" the white parts of the first one. But then I want to overlay that combined canvas on top of another background again, ...

Maybe? I have no idea. Where would I set that blend mode, before drawing the canvas or the overlay? I guess my main problem is that I have no idea how blend modes work, lol. None of the ways I try work, but I'm just doing it blindly here. Are there any good tutorials on blending?

Hey, I don't really understand blend modes, and am wondering if this is possible. I'm drawing a monochrome white and transparent black canvas, and I want to overlay that with a colored image.
