Purple legs!?

I'm a ftm with a 5 month old so I don't know what's normal and what's not. But every time anybody holds him including me, his legs get purple and have red spots on them. It doesn't matter which way you hold him it still happens. It starts happening normally like after 5 or so minutes. I have called his pediatrician and he goes Friday but I was just curious if this happened to anybody else's baby?
