ΔE 5.8, very close: most people won’t see a difference side by side. Aethermatic Blue is a little darker, warmer than Light Sky Blue. They are different kinds of paint: AMMO by Mig Light Sky Blue is an opaque base/layer paint and Citadel Aethermatic Blue is a one-coat contrast-style paint, so they won’t behave the same on the model even where the colour is close.
Yes, for most jobs. Very close match (ΔE 6). Aethermatic Blue is a little darker, warmer than Light Sky Blue. They are different kinds of paint.
The same difference applies the other way round: Light Sky Blue is a little lighter, 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.
