ΔE 3.8, very close: most people won’t see a difference side by side. Bronze is cooler than Mordant Earth. They are different kinds of paint: Citadel Mordant Earth is a technical paint or medium and Vallejo Bronze is a metallic, so they won’t behave the same on the model even where the colour is close.
Yes, for most jobs. Very close match (ΔE 4). Bronze is cooler than Mordant Earth. They are different kinds of paint.
The same difference applies the other way round: Mordant Earth is warmer.
ΔE is the colour difference between our two swatch estimates: under 2 is a perfect match (you’d struggle to tell them apart), under 6 very close, under 10 close, under 15 fair, under 20 loose, under 30 very loose, and 30 or more a poor match. Real paints also differ in finish, coverage and how they thin, so test before you commit.
