Only where an exact match doesn’t matter, such as a new unit or a highlight. Fair match (ΔE 11). Blushing Rose is a little lighter, more saturated, cooler than Tanned Flesh.
The same difference applies the other way round: Tanned Flesh is a little darker, more muted, warmer.
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.
