ΔE 13.0, fair: the same colour family, but not a straight swap. Bogey Green is a little lighter, more muted, cooler than Matt Military Green. They are different kinds of paint: AMMO by Mig Matt Military Green is an ink, glaze or transparent paint and Army Painter Bogey Green is an opaque base/layer 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 13). Bogey Green is a little lighter, more muted, cooler than Matt Military Green. They are different kinds of paint.
The same difference applies the other way round: Matt Military Green is a little darker, more saturated, 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.
