Dpts. 'DF10 Starbust' Different colors??

[Ysa]

Dtps. 'DF10 Starbust'
(Dpts. Green Field Sweet Valentine x Dpts. Chain Xen Pearl)

This has happen again in a different phal plant I don't know if you recall I will add the link to the other thread because I will like to know if this is normal or I'm doing something wrong that is causing the flowers to change colors.
I like the fact that they are kind of odd but I wonder if this is happening because I move them inside my house or my office when they are in bloom and obviously the light changes completely
