Yes, for most jobs. Very close match (ΔE 6). Flat Flesh is a little lighter, more muted than Solar Yellow.
The same difference applies the other way round: Solar Yellow is a little darker, more saturated.
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.
