Is it true that white will turn pink when the caliper gets too hot?

no, when it gets real hot, like on a track, it gets soft and the brake dust embeds in it, so it will darken and dull. But I have a friend here with a set of pearl white I did about 4 years ago that still look new, even after a few track days.

I am cutting back on the business now and no longer accepting new customers. I'm still here for previous customers and shops that I do work for but in a more limited capacity and my lifetime warranty still applies to all previously accomplished work.
