Lights default to bright after power out

Hi there, I have hue colour lights installed in my ceiling spots and also I have three in a light fitting at the rear of my TV. These are set to different colours to reflect of the wall behind the TV.
Whenever there is a power out to the house the ceiling spots are unaffected and return to their original settings and brightness.
Those behind the TV however default back to bright white and I have to set them again.
Any ideas why? Thanks.
