Notes

Stained Rocky (#1F2877) is a deep blue 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 (234°, 59%, 29%) 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.

Etymology

Stained
adjective

Old French desteindre, to discolor — past-participle of stain. As a color modifier, stained implies a deep-pigment-and-permanent quality where the hue has bonded with the substrate fiber. Sits at the deep-and-pigmented end of the grid, parallel to dyed and suffused in usage.

Rocky
noun

The North American mountain range — and the saturated deep blue of Rocky Mountain alpine lakes (Bear Lake, Sapphire Lake, Lake Louise) at high altitude. Rocky refers to Sapphire Lake in Montana's Glacier National Park: a saturated, slightly cool deep blue with the optical clarity of glacier-fed alpine lake.
