Dark forest teal
Or if you prefer - deep, vibrant sea-green.
Some tonal variegation :- deep bottle green; bright fir; deepest turquoise blue green; and a hint of cobalt. Occasional paler stipples: pale turquoise, light blue/green.
Overall darker than Calypso, but in the same range.
He's handsome, undoubtedly. Looks kinda expensive. Dangerous, this one...
