Plumb Merry Kingfisher

#2fa0ba
Notes

Plumb Merry Kingfisher (#2FA0BA) is a true 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 (191°, 60%, 46%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Plumb
adjective

Latin plumbum, lead — referring to the lead-weighted plumb-line of pre-modern carpentry. As a color modifier, plumb implies a clear-and-vertical-true quality where the hue carries the visual register of gravity-aligned-and-perfectly-vertical surface. Sits at the crisp-and-balanced end of the grid, parallel to level and squared in usage.

Merry
modifier

Old English myrige, pleasant-and-glad. As a color modifier, merry implies a glad-and-bright-and-festive quality, the visual register of Robin-Hood-Merry-Men-and-Maytime-merry hand-glad-and-bright-and-festive Robin-Hood-Merry-Men-and-Maytime-and-village-fair merried-and-glad-and-bright-and-festive surfaces under Robin-Hood-Merry-Men-and-Maytime-and-village-fair Sherwood-Forest-and-Mayday-and-Whitsun greenwood-festival-light. Sits at the modifier-and-mood end of the grid, parallel to jolly and blithe in usage.

Kingfisher
noun

The family Alcedinidae — particularly Alcedo atthis, the European common kingfisher whose iridescent turquoise-blue plumage gives the color its name. The color refers to a male European kingfisher's wing: a saturated, slightly cool deep blue-green with the iridescent satin finish of structurally colored feathers.
