Hyper Firuzeh
Hyper Firuzeh (#5CF3D1) 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 (166°, 86%, 66%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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
Greek hyper, over / beyond — sharing root with Latin super. As a color modifier, hyper implies a saturated-and-over-the-top-active quality where the hue exceeds normal visual amplitude with maximum-stimulation register. Sits at the bright-and-over-active end of the grid, parallel to manic and frenetic in usage.
The Persian word for turquoise — sourced from the Nishapur mines of Iran, used in Persian, Mughal, and Ottoman tile and jewelry for over four thousand years. Firuzeh tile defines the domes of the Shah Mosque in Isfahan. The color refers to fine Persian firuzeh: a saturated, slightly cool deep blue-green with the matte finish of fired faience.
