ΔE 4.9, very close: most people won’t see a difference side by side. Tomb King Tan is a little lighter, cooler than Matt Grime. They are different kinds of paint: AMMO by Mig Matt Grime is an ink, glaze or transparent paint and Army Painter Tomb King Tan is an opaque base/layer paint, so they won’t behave the same on the model even where the colour is close.
Yes, for most jobs. Very close match (ΔE 5). Tomb King Tan is a little lighter, cooler than Matt Grime. They are different kinds of paint.
The same difference applies the other way round: Matt Grime 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.
