Turquoise vs Nihilakh Oxide

How close are they?

ΔE 10.2, fair: the same colour family, but not a straight swap. Nihilakh Oxide is a little lighter, more muted, warmer than Turquoise. They are different kinds of paint: AMMO by Mig Turquoise is an opaque base/layer paint and Citadel Nihilakh Oxide is a technical paint or medium, so they won’t behave the same on the model even where the colour is close.
