ΔE 4.7, very close: most people won’t see a difference side by side. Transparent Yellow is more saturated than Golden Griffon. They are different kinds of paint: Citadel Golden Griffon is an opaque base/layer paint and Pro Acryl Transparent Yellow is an ink, glaze or transparent 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 5). Transparent Yellow is more saturated than Golden Griffon. They are different kinds of paint.
The same difference applies the other way round: Golden Griffon 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.
