My baby's inner lip color is dark/black

He is 2 weeks and 1 day old na po today, and since my mom is getting worried about his lip color i searched again sa google if ano po ba cause and meaning nito, pero po marami din pong nagsasabi na i should go and ask for a doctor but the situation here in our place is not yet that ok bawal parin po makalabas papuntang city :( sana po may makapag suggest or explain po sakin dito kung bakit po ganun kulay ng lips nya since birth po ganyan na po color ng lips ng LO ko.
