Unusual Pigmentation

[canis]

Hello!

I had this cat come through my work and was wondering what people thought of her coloring. She appears to be an extra dark tabby, but I've never quite seen one with this kind of pigmentation on their lips before. Random anomaly or is it called something specific?

Thanks!

Hi, I don't know if there's a name for it but I've seen that dark coloring on the mouth before.

Cant be common, but as she IS a darkish tabby, its easy to think there is extra coloration around the mouth...
