ΔE 5.5, very close: most people won’t see a difference side by side. Ironhull Grey is more muted than Gryph-Charger Grey. They are different kinds of paint: Citadel Gryph-Charger Grey is a one-coat contrast-style paint and Formula P3 Ironhull Grey is an opaque base/layer 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). Ironhull Grey is more muted than Gryph-Charger Grey. They are different kinds of paint.
