Yes, for most jobs. Very close match (ΔE 6). Pyrrole Red is a little darker than Legendary Red. They are different kinds of paint.
The same difference applies the other way round: Legendary Red is a little lighter.
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.
