Is primer the same as an undercoat?

Primers and undercoats serve similar purposes, but they're not the same thing. Primers create a good base for paint, while undercoats are designed to color a surface before painting. Undercoats are essentially tinted primers that help to create a more even color base for your final coat of paint.
