Sure Crete

#6fbec5
Notes

Sure Crete (#6FBEC5) 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 (185°, 43%, 60%) 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

Sure
adjective

Old French seur, certain — used as a color modifier since the medieval period for hues that read as confident and stable. Sure red, sure blue: moderate saturation combined with optical commitment. Sits at the crisp-bucket center alongside steady and true.

Crete
noun

The largest Greek island — and the saturated deep blue of Cretan beach water at Elafonissi and Balos Lagoon. Crete color refers to the lagoon at Balos: a saturated, slightly cool deep blue-green with the optical clarity of warm Aegean water filtered through pink-coral sand.
