ΔE 14.5, fair: the same colour family, but not a straight swap. Ungor Flesh is a little lighter, warmer than Khaki.
Only where an exact match doesn’t matter, such as a new unit or a highlight. Fair match (ΔE 15). Ungor Flesh is a little lighter, warmer than Khaki.
The same difference applies the other way round: Khaki is a little darker, cooler.
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.
