HELP! NEWBORN MOUTH BLUE!

He’s 2 days old, just brought him home and around his mouth is blue! Lips are pink and tongue is pink, he doesn’t seem phased but what is this?!?! Should I be worried???

UPDATE:

The blue color is just from him sucking on a pacifier for too long. Increased blood flow to his mouth. Happens with a bottle too but he’s perfectly fine
