They've really lightened up. I like it.
Is that variance genetic or a product of the environment?
I am not exactly sure, in an earlier post I tried to identify exactly what cultivar the plant was but my results were not 100% conclusive. African Violets are known to have some unstable genetics especially with hybrids called chimeras.
I believe that the light cycle in my house may differ from the greenhouse from where I purchased it as well as a slight difference in temperature and RH (relative humidity) may be at play for some of the change on color.
African Violets need at least 8 hours of darkness a day to produce florigen, a hormone that triggers blooming. This also reminds me of the Calvin cycle, its an important part of photosynthesis that does not require light to operate, its some dense material if you're interested.
