Mapped Hydrangea

#1c88aa
Notes

Mapped Hydrangea (#1C88AA) 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 (194°, 72%, 39%) 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

Mapped
adjective

Latin mappa, cloth / napkin — past-participle of map. As a color modifier, mapped implies a clear-and-cartographic-and-surveyed quality, the crisp color of Ordnance-Survey-and-USGS scientific-and-cadastral cartographic-and-topographic mapping-and-projection. Sits at the crisp-and-mapped end of the grid, parallel to plotted and surveyed in usage.

Hydrangea
noun

The genus Hydrangea — particularly H. macrophylla, whose flower color depends on soil pH (acidic = blue, alkaline = pink). The color refers to a blue-bloom H. macrophylla in acidic-soil garden: a saturated, slightly cool deep blue-violet with the matte finish of clustered four-petaled florets.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
