I need help with Photoshop!

[rowehessler]

Hey guys, so I'm really interested in doing cube art, but I can't figure out how to make the image in photoshop in mosaic form WITH only 6 colors. Are there any photoshop pros out there? I would greatly appreciate your help... message me if you know how to do this.

Here's one way to do it. Instructions are written for GIMP but it should be similar for Photoshop. One thing I would add would be to enable dithering when you convert your image to the new palette.
