ΔE 10.2, fair: the same colour family, but not a straight swap. Cobalt Turquois is a little lighter, cooler than Pine Hollow Shade. They are different kinds of paint: Army Painter Pine Hollow Shade is a wash/shade and Golden Cobalt Turquois 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 10). Cobalt Turquois is a little lighter, cooler than Pine Hollow Shade. They are different kinds of paint.
The same difference applies the other way round: Pine Hollow Shade is a little darker, 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.
