Only where an exact match doesn’t matter, such as a new unit or a highlight. Fair match (ΔE 13). Straken Green is a little lighter, cooler than Russian Green 4BO.

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.
