Thanks for the question - I don't remember the exact name and all paint producers name paint with a creative flair. What I'd offer is that when selecting colors from paint chips or similar, it should look more brown than you'd expect but will be great when painted in expanse. Brown/rust colors pick up salmon and pink colors easily and can be misleading in smaller chips so veer a browner direction if you're after a true "rust" color.

Never buy paint from a chip. Get samples and put on your walls. You can customize colors from good paint stores. Try BM or SW paints.
