ΔE 5.6, very close: most people won’t see a difference side by side. Mahogany Brown is a little lighter, cooler than Leather.
Yes, for most jobs. Very close match (ΔE 6). Mahogany Brown is a little lighter, cooler than Leather.
The same difference applies the other way round: Leather is a little darker, warmer.
ΔE is the colour difference between our two swatch estimates: under about 6 is close, over about 15 is loose. Real paints also differ in finish, coverage and how they thin, so test before you commit.
