ΔE 5.7, very close: most people won’t see a difference side by side. Peachy Flesh is a little lighter than Flesh. They are different kinds of paint: AMMO by Mig Flesh is an opaque base/layer paint and Army Painter Peachy Flesh is a one-coat contrast-style 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 6). Peachy Flesh is a little lighter than Flesh. They are different kinds of paint.
The same difference applies the other way round: Flesh 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.
