True Bora-Bora

#285e4d
Notes

True Bora-Bora (#285E4D) is a deep teal 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 (161°, 40%, 26%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

True
adjective

Old English trēowe, faithful — used as a color modifier since the seventeenth century for hues that read as the canonical version of their family. True red, true blue: the saturation is full, the hue is neither shifted nor adulterated. Sits at the center of the bold and crisp buckets, marking the unequivocal middle of any chromatic family.

Bora-Bora
noun

The volcanic atoll in French Polynesia — and the saturated turquoise of its central lagoon ringed by motu coral islets. Bora-Bora color refers to the lagoon at sunset: a saturated, slightly cool deep blue-green with the optical complexity of light filtering through volcanic-ringed water.
