The top photo below this set is not a Christmas cactus rather an Easter cactus which is now in full bloom and Easter is in two days - time, eh?  So here is a photo of the center of the bloom now that the pistils have grown thru the stamens —

The E.cactus below has the pollen dotted around on it's leaves - gold against purple, Royalty.

While the same color, the lighting is a bit different for each as it was a different day and different time.
