ΔE 10.6, fair: the same colour family, but not a straight swap. Dusken Green is more muted, warmer than Waystone Green. They are different kinds of paint: Citadel Waystone Green is a technical paint or medium and Vallejo Dusken Green is a metallic, 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). Dusken Green is more muted, warmer than Waystone Green. They are different kinds of paint.
The same difference applies the other way round: Waystone Green is more saturated, cooler.
ΔE is the colour difference between our two swatch estimates: under 2 is a perfect match (you’d struggle to tell them apart), under 6 very close, under 10 close, under 15 fair, under 20 loose, under 30 very loose, and 30 or more a poor match. Real paints also differ in finish, coverage and how they thin, so test before you commit.
