Only where an exact match doesn’t matter, such as a new unit or a highlight. Fair match (ΔE 12). Demon Red is a little darker, more saturated, warmer than Raging Rose.
The same difference applies the other way round: Raging Rose is a little lighter, 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.
