ΔE 10.0, fair: the same colour family, but not a straight swap. Forbidden Fruit is more muted, warmer than Lilac.
Only where an exact match doesn’t matter, such as a new unit or a highlight. Fair match (ΔE 10). Forbidden Fruit is more muted, warmer than Lilac.
The same difference applies the other way round: Lilac is more saturated, 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.
