Iridescent Pearl (Fine) vs Rust (Metallic)

How close are they?

ΔE 3.4, very close: most people won’t see a difference side by side. Our swatches for the two are almost the same. They are different kinds of paint: Golden Iridescent Pearl (Fine) is a pearl paint and Vallejo Rust (Metallic) is a metallic, so they won’t behave the same on the model even where the colour is close.
