Straightforward Oasis

#578778
Notes

Straightforward Oasis (#578778) is a true 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°, 22%, 44%) places it in the muted 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.

Oasis
noun

A fertile spot in a desert — particularly the date-palm oases of the Sahara and Arabian peninsula. Oasis color refers to the unifying blue-green of a Saharan oasis pool surrounded by date palms: a saturated, slightly cool deep blue-green with the optical clarity of mineral-spring water.
