Quiet Morningglory

#2b5159
Notes

Quiet Morningglory (#2B5159) is a deep cyan with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (190°, 35%, 26%) 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. 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

Quiet
adjective

Latin quietus, at rest — used as a color modifier since the medieval period for hues that read as restrained. Quiet pink, quiet blue: low saturation combined with optical calmness. Sits across the crisp and hushed buckets where the color is present but doesn't ask for attention.

Morningglory
noun

The family Convolvulaceae — particularly Ipomoea purpurea, the climbing annual whose blue-purple morning-blooming trumpet flowers close by midday. The color refers to a fresh Ipomoea flower in early morning: a saturated, slightly cool deep blue-violet with the satin finish of single-day trumpet bloom.
