Candid Skullcap

#518dd0
Notes

Candid Skullcap (#518DD0) is a true azure 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 (212°, 57%, 57%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Candid
adjective

Latin candidus, bright-white / honest — derived from candēre (to shine). As a color modifier, candid implies a clear-and-honest-and-direct quality where the hue carries the visual register of straightforward-honest declaration. Sits at the crisp-and-honest end of the grid, parallel to frank and plainspoken in usage.

Skullcap
noun

The genus Scutellariaskullcap, mint-family perennials whose helmet-shaped blue flowers and herbal medicinal properties have been used in Chinese, North American, and European traditional medicine. The color refers to a fresh S. baicalensis bloom: a saturated, slightly cool deep blue-violet with the matte finish of bilateral bracted flower.
