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.

Kona
noun

The leeward (western) coast of the Big Island of Hawaii — and the deep blue-green of Kona's Kealakekua Bay and Honaunau coves. Kona color refers to the bay water at midday: a saturated, slightly cool deep blue-green with the optical clarity of cold Pacific water against volcanic black-sand beaches.
