Subdued Morningglory

#536f6e
Notes

Subdued Morningglory (#536F6E) is a true 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 (178°, 14%, 38%) places it in the muted 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

Subdued
adjective

The past participle of subdue, to bring under control — used as a color modifier since the seventeenth century for hues that have been reduced from their natural saturation. Subdued red, subdued green: low-to-moderate saturation combined with optical restraint. Sits at the hushed-bucket alongside muted and tempered.

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.
