Which paint colors require gray primer

paintingprimer

I was told that red and deep blue paints required gray (high hiding) primer. I used it before I painted my living room red. But how do I know which other paint colors do vs. just regular white primer?

E.g., I'm getting ready to paint some millwork coffee brown-ish. Should I use gray or is white fine?

I'd consider any color that's darker than the gray primer itself to be better suited to gray primer. It's not just about color hiding, but also edge exposure. If you prime with white and then paint a dark or bold color, it's possible that fringe white will show where you've masked, etc.
