ΔE 12.8, fair: the same colour family, but not a straight swap. Yellow Glaze is a little lighter, much more saturated than Hexos Palesun. They are different kinds of paint: Citadel Hexos Palesun is an opaque base/layer paint and Two Thin Coats Yellow 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 13). Yellow Glaze is a little lighter, much more saturated than Hexos Palesun. They are different kinds of paint.
The same difference applies the other way round: Hexos Palesun is a little darker, much more muted.
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.
