ΔE 4.3, very close: most people won’t see a difference side by side. Eldar Flesh is a little lighter than Matt Sepia. They are different kinds of paint: AMMO by Mig Matt Sepia is an ink, glaze or transparent paint and Citadel Eldar Flesh 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 4). Eldar Flesh is a little lighter than Matt Sepia. They are different kinds of paint.
The same difference applies the other way round: Matt Sepia is a little darker.
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.
