I'm trying to convert an image to a five color (R, O, Y, B, and White) dithered image to use as a template for creating a Rubik's Cube mosaic using 600 cubes. I can scale the image to an appropriate size but don't know how to convert colors and make it look good. Very Very Very new to this... as in this is my first project. (Way to jump right in). Any help would be truly appreciated.

I created a quick and easy tutorial for this, it's in the tutorials section.

"Rubikubism"

Found this cool online program that does this; pretty cool stuff.

Yeah, my tut doesn't cover green. Multi threshold filter uses only 5 colors, and OP wanted 5.
Have to think another method for 6 colors.

Thank you!!! Working on it today. Appreciate the help. Will let you know how it goes!
