ΔE 11.3, fair: the same colour family, but not a straight swap. Dark Angels Green is a little darker, more muted, warmer than Dark Green INK. They are different kinds of paint: AK Interactive Dark Green INK is an ink, glaze or transparent paint and Citadel Dark Angels 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 11). Dark Angels Green is a little darker, more muted, warmer than Dark Green INK. They are different kinds of paint.
The same difference applies the other way round: Dark Green INK is a little lighter, more saturated, cooler.
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.
