Dependable Gyokuro

#89fbf2
Notes

Dependable Gyokuro (#89FBF2) is a soft 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 (175°, 93%, 76%) places it in the highly saturated band at a light 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

Dependable
adjective

Latin dē-pendere, to hang from — adjectival suffix -able. As a color modifier, dependable implies a clear-and-trustworthy-and-consistent quality where the hue carries the visual register of consistently-performing-and-counted-on design-element. Sits at the crisp-and-honest end of the grid, parallel to reliable and trustworthy in usage.

Gyokuro
noun

The premium Japanese green tea grown in shade for three weeks before harvest — concentrating chlorophyll and theanine. Gyokuro (玉露 — jewel dew) is the most expensive non-matcha Japanese tea. The color refers to fresh-brewed gyokuro: a saturated, slightly cool deep blue-green with the optical depth of shaded-leaf tea.
