Substantial Sari Royal

#253e9e
Notes

Substantial Sari Royal (#253E9E) is a true blue 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 (228°, 62%, 38%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Substantial
adjective

Latin substantia, substance — adjectival suffix -al, derived from sub-stāre (to stand under). As a color modifier, substantial implies a saturated-and-weighty-and-material quality where the hue carries visual mass and presence. Sits at the bold-and-weighty end of the grid, parallel to weighty and hefty in usage.

Sari
modifier

Sanskrit śāṭī, long-draped-cloth. As a color modifier, sari implies an Indian-sari-and-Banarasi-and-Kanjeevaram-silk quality, the visual register of Banarasi-and-Kanjeevaram-sari hand-Indian-sari-and-Banarasi-and-Kanjeevaram-silk Banarasi-and-Kanjeevaram-sari-and-Mysore-and-Bengal-cotton sari-and-Indian-sari surfaces under Banarasi-and-Kanjeevaram-sari-and-Mysore-and-Bengal-cotton Varanasi-and-Kanjeevaram-and-Mysore-loom Indian-loom-light.

Royal
noun

The blue of European royal court dress and regalia from the late seventeenth century forward — the color of British peers' robes, French royal sashes, the lining of the crown-jewel cases. The color refers to a saturated, slightly violet-shifted blue with the matte finish of velvet or melton wool dyed to maximum intensity: deeper than cornflower, warmer than ultramarine, with the heraldic weight of a color reserved for monarchs and the official Crown.
