ΔE 12.0, fair: the same colour family, but not a straight swap. Naphthol Red Light is a little darker, more muted than Raging Rose. They are different kinds of paint: Army Painter Raging Rose is an opaque base/layer paint and Golden Naphthol Red Light 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 12). Naphthol Red Light is a little darker, more muted than Raging Rose. They are different kinds of paint.
The same difference applies the other way round: Raging Rose is a little lighter, more saturated.
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.
