Tidy Ophiuchus Teal

#91c1be
Notes

Tidy Ophiuchus Teal (#91C1BE) is a true cyan with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (176°, 28%, 66%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Tidy
adjective

Old English tidig, timely — drifted in modern English to mean neat, orderly. Used as a color modifier for hues that read as composed and unfussy. Tidy beige, tidy gray: moderate saturation combined with optical neatness. Sits at the crisp-bucket alongside plain and modest.

Ophiuchus
modifier

Greek Ὀφιοῦχος, serpent-bearer. As a color modifier, ophiuchus implies a serpent-bearer-and-thirteenth-sign-and-Asclepius quality, the visual register of Hellenic-Ophiuchus-and-Asclepius-serpent-bearer hand-serpent-bearer-and-thirteenth-sign-and-Asclepius Hellenic-Ophiuchus-and-Asclepius-serpent-bearer-and-Rod-of-Asclepius ophiuchus-and-serpent-bearer-and-thirteenth-sign surfaces under Hellenic-Ophiuchus-and-Asclepius-serpent-bearer-and-Rod-of-Asclepius autumn-and-November-and-December serpent-bearer-light. Sits at the modifier-and-zodiac end of the grid, parallel to scorpio and sagittarius in usage.

Teal
noun

Anas crecca, the small dabbling duck whose male in breeding plumage sports a chestnut head crossed by a glossy green-blue stripe. The color refers to that stripe — the iridescent panel just behind the eye: a saturated, slightly muted blue-green with the optical depth of structural color rather than pigment. Cooler than cypress, warmer than cerulean, with the ornithological specificity of a color named for one feather of one bird.
