ΔE 12.1, fair: the same colour family, but not a straight swap. Violent Vermillion is noticeably lighter than Candy Red. They are different kinds of paint: AMMO by Mig Candy Red is an ink, glaze or transparent paint and Army Painter Violent Vermillion is an opaque base/layer 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). Violent Vermillion is noticeably lighter than Candy Red. They are different kinds of paint.
The same difference applies the other way round: Candy Red is noticeably darker.
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.
