Lordly Stratus

#2a7efd
Notes

Lordly Stratus (#2A7EFD) is a true azure with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (216°, 98%, 58%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Lordly
adjective

Old English hlāford-līc, lord-like — adjectival suffix -ly. As a color modifier, lordly implies a saturated-and-aristocratic-and-haughty quality, the deep-rich color of pre-modern English-and-French manorial-aristocracy livery and hereditary-estate household-textile. Sits at the bold-and-aristocratic end of the grid, parallel to princely and patrician.

Stratus
noun

The Latin meteorological term for layer cloud — the low, gray-blue overcast clouds that cover the entire sky in mid-latitude winters. Stratus refers to a fully developed stratus deck on a North Sea winter morning: a soft, slightly muted deep blue-gray with the optical density of homogeneous low cloud.
