ΔE 12.5, fair: the same colour family, but not a straight swap. Galvanic Corrosion is a little lighter, more saturated, warmer than Snakebite Leather. They are different kinds of paint: Citadel Snakebite Leather is a one-coat contrast-style paint and Vallejo Galvanic Corrosion is a fluorescent or effect 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 12). Galvanic Corrosion is a little lighter, more saturated, warmer than Snakebite Leather. They are different kinds of paint.
The same difference applies the other way round: Snakebite Leather 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.
