ΔE 5.9, very close: most people won’t see a difference side by side. Tiger Eye Brown is more saturated than Gore-Grunta Fur. They are different kinds of paint: Citadel Gore-Grunta Fur is a one-coat contrast-style paint and Green Stuff World Tiger Eye Brown is an ink, glaze or transparent paint, so they won’t behave the same on the model even where the colour is close.
