Yes, for most jobs. Very close match (ΔE 6). Desert Tan is a little lighter, cooler than Light Earth.
The same difference applies the other way round: Light Earth is a little darker, 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.
