Last night I had the idea to use two colors schemes alternatingly. With independent colors, so twelve colors overall. Can be done for single cube attempts as well as inside multiblind attempts. Alternate, so cubes 1,3,5,... use one scheme and 2,4,6,... use the other. The reason is that I rely on short term memory or a "feeling" for what I've covered in the current cube already, and sometimes confuse it with the previous cube. Having different colors and according different memo images could help.
