Velvety Sora

#1154a5
Notes

Velvety Sora (#1154A5) is a true azure with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (213°, 81%, 36%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Velvety
adjective

An adjectival form of velvet, used since the eighteenth century for colors that read as if they had the matte light-absorbing quality of velvet. Implies high saturation combined with a non-glossy surface — the matte richness of a deep wine in a fabric rather than in a glass. Sits in the bold-and-deep corner of the grid alongside plush and lush.

Sora
noun

The Japanese word for sky — and sora-iro (空色), the standard Japanese name for sky-blue. Used in Heian-period waka poetry and ukiyo-e woodblock prints for the saturated mid-blue of clear summer skies. The color refers to a Japanese summer sky at midday: a saturated, slightly cool deep blue with the optical brightness of mid-latitude scattered sunlight.
