Only where an exact match doesn’t matter, such as a new unit or a highlight. Fair match (ΔE 12). Werewolf Brown is a little lighter, more muted, cooler than Wyldwood.
The same difference applies the other way round: Wyldwood 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.
