ΔE 10.4, fair: the same colour family, but not a straight swap. Algae Green is a little lighter, more saturated than Military Green. They are different kinds of paint: AMMO by Mig Military Green is an ink, glaze or transparent paint and Army Painter Algae Green is a one-coat contrast-style paint, so they won’t behave the same on the model even where the colour is close.
Only where an exact match doesn’t matter, such as a new unit or a highlight. Fair match (ΔE 10). Algae Green is a little lighter, more saturated than Military Green. They are different kinds of paint.
The same difference applies the other way round: Military Green is a little darker, more muted.
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.
