I've tried out many shades of colours. I staryed off with the cubesmith standard set. I hated how close together the green and blue were so I ordered fluo green from cubesmith. Then I realized that havig only one bright colour was too distracting and I had trouble recognizing the other colours in a solve. I decided to make a big cubesmith order and got many differet shades of colours. There was bright blue, light green, bright orange, fluo colours, black, and lots more. I put different sets on different cubes (all black btw) and decidedto use a cubesmith fluorescent set. The red and orange didn't look too good for me so I used bright orange. I also swapped white with light gray. This is by far the best colour scheme I could find
btw I can post pictures of my cube or something but I'm on my iPod at the moment
I like dark colors on sides and white and fluro yellow on top. Makes recognition on f2l and LL so much easier. (assuming you do white cross and yellow cross only)
