Bountiful Chicago

#3357a5
Notes

Bountiful Chicago (#3357A5) is a true azure 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 (221°, 53%, 42%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Bountiful
adjective

Old French bonté, goodness — adjectival suffix -ful. As a color modifier, bountiful implies a saturated-and-generous-and-abundant quality where the hue offers visual richness without measure. Sits at the bold-and-saturated end of the grid, parallel to abundant and plentiful in usage.

Chicago
noun

The American Midwestern city on Lake Michigan — and the deep blue of Lake Michigan, the Chicago city flag (four red stars on white-and-blue field), and the Chicago Bears NFL team uniform. Chicago refers to Lake Michigan from the Lakefront Trail at midday: a saturated, slightly cool deep blue.
