ΔE 10.2, fair: the same colour family, but not a straight swap. Dusken Green is warmer than Leviathan.
Only where an exact match doesn’t matter, such as a new unit or a highlight. Fair match (ΔE 10). Dusken Green is warmer than Leviathan.
The same difference applies the other way round: Leviathan is cooler.
