ΔE 10.6, fair: the same colour family, but not a straight swap. Burnt Sienna is more saturated, warmer than Tuskgor Fur. They are different kinds of paint: Citadel Tuskgor Fur is an opaque base/layer paint and Golden Burnt Sienna is an ink, glaze or transparent 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 11). Burnt Sienna is more saturated, warmer than Tuskgor Fur. They are different kinds of paint.
The same difference applies the other way round: Tuskgor Fur is 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.
