Calm Galapagos

#28a388
Notes

Calm Galapagos (#28A388) is a true teal 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 (167°, 61%, 40%) places it in the balanced 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

Calm
adjective

Latin calma, heat of the day — paradoxically drifted in Italian to mean stillness. Used as a color modifier since the seventeenth century for hues that read as untroubled. Calm blue, calm gray: moderate saturation combined with optical quiet. Sits at the crisp-bucket near quiet and steady.

Galapagos
noun

The Ecuadorian volcanic archipelago — Darwin's evolutionary laboratory — and the saturated blue-green of Galapagos lagoon water at Bartolomé Island. Galapagos refers to the cove at Bartolomé: a saturated, slightly cool deep blue-green with the optical clarity of cold Pacific upwelling waters.
