ΔE 5.6, very close: most people won’t see a difference side by side. Ink Skin is more saturated, cooler than Traitor Red. They are different kinds of paint: Army Painter Traitor Red is an opaque base/layer paint and Vallejo Ink Skin is an ink, glaze or transparent paint, so they won’t behave the same on the model even where the colour is close.
Yes, for most jobs. Very close match (ΔE 6). Ink Skin is more saturated, cooler than Traitor Red. They are different kinds of paint.
The same difference applies the other way round: Traitor Red is more muted, 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.
