My Moon Cactus

I bought a yellow moon cactus almost 12 months ago as I liked its shade of yellow/orange, and thought it would compliment the Mini African Violet that I bought at the same time.

I did noticed straight away that it has a couple of tiny buds in pinkish red colour but didn't thought much about it until several weeks later I noticed the yellow part was turning orange/red in colour!!

I searched online for the cause of the colour change but found no information on it, except that the yellow, orange, pink or red variants in these cactus are actually a mutation from their typical green colour. None of the pages mentioned anything about it changes colour during its life span.

I am a little disappointed that my yellow moon cactus didn't stay yellow. If I wanted an orange moon cactus, I would have bought an orange one in the first place... :(
