Hospitable Morningglory

#3797a4
Notes

Hospitable Morningglory (#3797A4) 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 (187°, 50%, 43%) 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

Hospitable
adjective

Latin hospitābilis, of-the-host — adjectival suffix -able. As a color modifier, hospitable implies a clear-and-cordial-and-welcoming quality where the hue carries the visual register of Bed-and-Breakfast and country-inn warm-cordial-host atmosphere. Sits at the crisp-and-cheerful end of the grid, parallel to welcoming and inviting 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.
