ΔE 11.0, fair: the same colour family, but not a straight swap. Warpstone Glow is a little lighter, more saturated, warmer than Goblin Green.
Only where an exact match doesn’t matter, such as a new unit or a highlight. Fair match (ΔE 11). Warpstone Glow is a little lighter, more saturated, warmer than Goblin Green.
The same difference applies the other way round: Goblin Green is a little darker, more muted, 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.
