ΔE 10.8, fair: the same colour family, but not a straight swap. Chromium Oxide Green is more saturated, cooler than Commando Green. They are different kinds of paint: Army Painter Commando Green is an opaque base/layer paint and Golden Chromium Oxide Green is an ink, glaze or transparent 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). Chromium Oxide Green is more saturated, cooler than Commando Green. They are different kinds of paint.
The same difference applies the other way round: Commando Green is more muted, 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.
