two coloured mug surface help pls

Hi, I am on a small project , in which I need to design a mug, which has two colours. I am good at designing entire model without any problem, but I just cant get inside surface white, and outer surface orange. maybe, is it vertex paint? thanks

Objects can have multiple materials applied to them. Assign one material to the inside faces and another material to the outside faces.

wow, thank you very much, exactly what i was looking for :slight_smile:
just want to share this quick result below …thanks again Richard
