First bloom magic

[TZ-Someplace]

It was not supposed to have the red ring around the petals and lip. Neither parent had that. I am wondering if it is luck of the draw from the genetics or if growing the bud cool (low to mid 60s) contributed (I read someplace that cool temp bud development enhances/darkens color). I guess I'll find out from the other two plants of the same cross but they won't bloom until hot weather.
