ΔE 12.6, fair: the same colour family, but not a straight swap. Inktense Olive is a little darker, more saturated, cooler than Skavenblight Dinge. They are different kinds of paint: Citadel Skavenblight Dinge is an opaque base/layer paint and Scale75 Inktense Olive 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 13). Inktense Olive is a little darker, more saturated, cooler than Skavenblight Dinge. They are different kinds of paint.
The same difference applies the other way round: Skavenblight Dinge is a little lighter, 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.
