The buds have been big since before Christmas, but this cactus waited until the New Year to bloom. I suppose that would make it a New Year’s cactus?
The buds were pink and the bud which has not yet opened is also dark pink, but after opening, it seems more red than pink. In any case, that’s what the camera picked up.
The leaves are translucent, so how red or pink the blossom appears depends on the light.
It was a sunny day. I had to wait until the sun wasn’t directly on the flower. I need the brightness of the sun, but in full sun, parts of the flower burn out and processing the pictures becomes problematic.
