Only where an exact match doesn’t matter, such as a new unit or a highlight. Fair match (ΔE 12). Kraken Skin is a little lighter, warmer than Spectral Green.
The same difference applies the other way round: Spectral Green is a little darker, 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.
