Inviting Bottomless

#73e8f6
Notes

Inviting Bottomless (#73E8F6) is a soft 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 (186°, 88%, 71%) places it in the highly saturated band at a light 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

Inviting
adjective

Latin invītāre, to invite — present-participle of invite. As a color modifier, inviting implies a clear-and-cordial-and-encouraging quality where the hue carries the visual register of warm-inviting-and-encouraging entrance-foyer color tone. Sits at the crisp-and-cheerful end of the grid, parallel to welcoming and hospitable in usage.

Bottomless
noun

A descriptor for water deep enough that the bottom isn't visible from above — particularly cenote sinkholes, deep ocean trenches, and Caribbean blue holes. Bottomless color refers to the Great Blue Hole of Belize seen from above: a saturated, slightly cool very deep blue with the optical depth of unfathomably deep water.
