The 'green' catts often change colors as the flowers mature. Or, it
could be a cultural thing. I have certain plants that have different
colored flowers depending on I'm not sure what. Slc. Crystelle Smith is
one, the flower color is quite variable, from pink to lavendar,
sometimes on the same inflorescence. I think it is temperature
dependent, or perhaps light, and the color depends on exactly what the
very small bud received in development. I know that a lot of phrags
(mainly besseae hybrids) are quite sensitive to temperature during
flower development, and this can greatly influence the amount of red
color in the final flower.

Cool though!
