Trim Morningglory

#378eb4
Notes

Trim Morningglory (#378EB4) 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 (198°, 53%, 46%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Trim
adjective

Old English trymman, to make firm — sharing root with firm. As a color modifier, trim implies a clear-and-neatly-arranged quality where the hue carries the visual register of carefully-edited surface-detail. Sits at the crisp-and-neat end of the grid, parallel to neat and tidy in usage.

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.

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.
