Cyrtanthus falcatus—green flowers

Bob beat me to that comment, but it's widely accepted in orchid circles
that cooler temperatures, especially in combination with brighter light,
yield more intense flower colors, sometimes dramatically so.
I haven't seen (or looked for) any research on the topic, but I've seen
multiple flowers that developed in different temperature conditions that
were so different in color I'd never have believed they were from the
same plant if I hadn't had it in front of me.
But I think it's quite nice as it is.

I agree with Arnold, and my one suggestion, based on complete ignorance of Cyrtanthus but observations of many other things, is that much cooler conditions can enhance the production of anthocyanins. So moving it outside any time the temps are above freezing might bring out more of the red. Just a thought.
And it does have a subtle beauty, nicely captured in the image.
