1. An electronic device operable in an environment with ambient light, comprising:
a housing;
a display in the housing;
a color flicker sensor that measures changes in the ambient light over time to produce color flicker sensor data; and
control circuitry in the housing that:
transforms the color flicker sensor data with a frequency transform to produce frequency component information for the color flicker sensor data; and
adjusts a white point associated with the display using the frequency component information.
