Why do some white LEDs start emitting an almost bluish tone over time?

The white LEDs are made of phosphor coated blue LED chip. The degradation of the phosphor layer over time causes the bluish tone of the light emitted. This degradation is most likely to be caused by the chip running too hot. Remote phosphor technology overcomes this issue.
