Hi! I was planning on making a few greyscale cubes and wanted some opinions. Apparently, there are two different "correct" ways to sticker them. You can either use the same color scheme as the Rubik's Icon, or you can do the true greyscale (which shades of grey coordinate to the original color in the color scheme). After checking out forum posts it seems that most people lean towards the Rubik's Icon version, but I just thought I'd see what you guys think. Which would you prefer? Thanks!
