ΔE 14.1, fair: the same colour family, but not a straight swap. Orange Glaze is a little lighter, much more muted than Radiation Glow. They are different kinds of paint: Army Painter Radiation Glow is an opaque base/layer paint and Two Thin Coats Orange Glaze 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 14). Orange Glaze is a little lighter, much more muted than Radiation Glow. They are different kinds of paint.
The same difference applies the other way round: Radiation Glow is a little darker, much 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.
