ΔE 4.1, very close: most people won’t see a difference side by side. Ryza Rust is more saturated than Orange. They are different kinds of paint: AMMO by Mig Orange is an ink, glaze or transparent paint and Citadel Ryza Rust 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 4). Ryza Rust is more saturated than Orange. They are different kinds of paint.
The same difference applies the other way round: Orange is 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.
