Why would an ordinary, white screw-in flourescent bulb start glowing entirely in a bright pinkish lavender color?

It’s gonna esplode!!!

Actually I have no idea

Unfortunately, it is failing. There is no way to tell if the built in ballast or the bulb is the culprit, but they are not separately changable.

it is exploring it’s femenine side

Make sure that you don’t have the bulb on a “dimmer.” (That’s not good for compact flourescents.)
Otherwise, I agree with mac316, and I would guess its dead or dying. No user-serviceable parts either.

flourescent bulbs don’t work on dimmers. The bulb is failing. Take it back.

is it embarrassed about something perhaps?
