Is it normal for my dog to have pink spots inside his mouth?

My dog seems to have this pinkish/skin coloured part inside his mouth. It doesn’t seem to hurt him or anything. I’m curious to what it actually is, if it’s harmful or not normal.

Thank you for taking multiple pictures and circling the areas. That was very helpful. The areas that you circled are a normal part of the lips and gums called the commissures. Ace has some freckling of his mouth tissue, so he has both black and pink areas of this gums. His commissures appear a little more prominent since they are pink, but they look completely normal. I hope that was helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.
