Can I use Off-White instead of Sky?

Can I use Sky instead of Off-White?

The same difference applies the other way round: Sky is more saturated, 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.
