A small collection of octahedrons (standard, octaminx, okki, Trajber's, face turning, skewb diamond):
Does anyone know whether there is an "official" color scheme for the standard octahedron/star puzzler? I noticed that my octahedrons all have different color patterns. Two of them (including the sealed one) have red opposite orange, blue opposite yellow, purple opposite gold, and white opposite green. But their color arrangements are still different, since the sealed one has a red-blue-gold-white corner (going clockwise), while the other one has a red-blue-white-purple corner. The third octahedron has red opposite orange, blue opposite green, purple opposite yellow and white opposite gold, and the corresponding corner is red-blue-purple-white.
I just discovered that Aleksey asked a similar question in this post
a few years ago, so I guess there might not be any standard color arrangements for the octahedrons.
