How to dither two colors like a checkerboard - RealWorld forums

I want to use a tool that alternates between two colors and two pixels, like a checkerboard. Is there a code to do this on RW Paint? Also, can you make the code, so that I can use the mouse to draw these dithered colors?

nevermind, i found out that i can do this with the brush, lasso, pencil and fill tools

cool
