Symmetrical Lithodora

#1298b5
Notes

Symmetrical Lithodora (#1298B5) is a true 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 (191°, 82%, 39%) places it in the highly saturated band at a mid 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

Symmetrical
adjective

Greek symmetría, due-proportion — adjectival suffix -al, derived from sym-metron (with-measure). As a color modifier, symmetrical implies a clear-and-balanced-and-mirrored quality where the hue carries the visual register of bilateral-or-radial proportional symmetry. Sits at the crisp-and-balanced end of the grid, parallel to balanced and aligned in usage.

Lithodora
noun

The genus Lithodora — Mediterranean rock-garden ground covers with intensely deep-blue flowers. L. diffusa 'Heavenly Blue' is among the most saturated blue flowers grown in temperate gardens. The color refers to a fresh L. diffusa mat in flower: a saturated, slightly cool deep blue with the matte finish of small five-petaled flower.
