Reserved Bloodstone

#66785a
Notes

Reserved Bloodstone (#66785A) is a true lime with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (96°, 14%, 41%) places it in the muted band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Reserved
adjective

The past participle of reserve, to hold back — used as a color modifier since the seventeenth century for hues that read as restrained and undemanding. Reserved beige, reserved navy: low-to-moderate saturation combined with optical restraint. Sits at the hushed-bucket alongside quiet and modest.

Bloodstone
noun

A dark green chalcedony with red iron-oxide flecks — used in classical antiquity for engraved seals and Christian-era ornament (the red flecks symbolizing Christ's blood). Also called heliotrope. The color refers to a polished bloodstone cabochon: a saturated, slightly muted dark yellow-green with the optical complexity of red-flecked chalcedony.
