Moon cactus--How old can they get, and what colours do they come in I have a red one, a pink one, a purple one and two different shades of yellow. Just wondered if there are other colours, anyone knows of

I searched for orange moon cactus and came up with few results but I guess this one used to be yellow and is now orange:

My yellows are still yellow, but I have seen them starting to go slightly orange. They definately are different. I love the colours I have found so far. Still look for different colours, but haven't found any so far.
