Open Sway Kingfisher

Old English open, unobstructed — used as a color modifier since the eighteenth century for hues that read as airy or uncrowded. Open blue, open green: moderate saturation combined with optical spaciousness, the slight visual breath of a hue that doesn't crowd the surface it covers. Sits at the crisp-bucket center alongside clear.

Middle English swēven, to-move-side-to-side. As a color modifier, sway implies a side-to-side-and-rocking-and-rhythmic quality, the visual register of willow-branch-and-tall-grass-sway hand-side-to-side-and-rocking-and-rhythmic willow-branch-and-tall-grass-and-pendulum-clock swayed-and-side-to-side-and-rocking-and-rhythmic surfaces under willow-branch-and-tall-grass-and-pendulum-clock breeze-rocked-and-pendulum-and-cradle riverbank-meadow-light. Sits at the modifier-and-mood end of the grid, parallel to drift and float in usage.

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.
