Friendly Eclipse

#0a0d2a
Notes

Friendly Eclipse (#0A0D2A) is a deep 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 (234°, 62%, 10%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Friendly
adjective

Old English frēondlīc, friend-like — adjectival suffix -ly. As a color modifier, friendly implies a neutral-and-welcoming-and-approachable quality, the neutral color of American-Country-and-English-Cottage friendly-and-welcoming-hosting interior-decoration-and-textile coordinated-color tone. Sits at the neutral-and-friendly end of the grid, parallel to amiable and cordial in usage.

Eclipse
noun

The total occlusion of the sun by the moon — the brief event during which the sky goes from full daylight to deep blue-black in the four to seven minutes of totality. The color refers to the sky at the centerline of total eclipse: a deep, slightly violet-shifted near-black with the optical complexity of a sky still receiving the sun's corona. Cooler than midnight, warmer than vantablack, with the celestial weight of a phenomenon visible at any single location once every few centuries.
