Brown or Light red RBTA

I have seen quite a few people with light colored rbta's or even brown ones. Just wondering what kind of light u guys are using? Is it a light issue or the lineage of the anemone? Even when my lights are out, the anemone is still bright red.
I'm not trying to bash anyone, just curious. If it's a lineage/offspring issue, I would think u would have little control over the strength of the color.
I am currently using kessil leds and metal halide. The anemone prefers to be directly under the 10k halide
