Baby's skin tone

Alexis
Hey ladies, 
I just want to ask, do your little one skin tone change color on a daily basis? My little one can be super light skin in the morning then dark in the midday and then light again... He is constantly changing skin tone. 
It's definitely not the lighting. He had jaundice the first two weeks and he's now 7weeks. I just want to know if anyone is experiencing the same thing? Is this normal? I know he will change skin tone but he is constantly changing back and forth at least twice q day.
