Straightforward Glassy

#28a090
Notes

Straightforward Glassy (#28A090) 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 (172°, 60%, 39%) 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

Straightforward
adjective

English compound straight + forward — sharing root with German geradeaus. As a color modifier, straightforward implies a clear-and-direct-and-unencumbered quality where the hue carries the visual register of clear-aim-and-uncomplicated character. Sits at the crisp-and-honest end of the grid, parallel to candid and direct in usage.

Glassy
noun

A descriptor for very calm water surface — used in maritime vocabulary for sea conditions when wind is below 1 knot and the surface reflects like polished glass. Glassy color refers to a glassy-calm tropical lagoon at dawn: a saturated, slightly cool deep blue-green with the mirror-finish optical complexity of unbroken water.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
