Bountiful Bluebell

#6365dc
Notes

Bountiful Bluebell (#6365DC) is a true blue with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (239°, 63%, 63%) 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 yellow. 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.

Bluebell
noun

Hyacinthoides non-scripta, the wild English bluebell that carpets ancient British woodlands in late April — half the world's population grows in the United Kingdom. The color refers to a freshly opened bluebell flower: a saturated, slightly violet-shifted blue with the matte finish of a downward-hanging bell. Cooler than periwinkle, warmer than cobalt, with the seasonal weight of a flower so closely tied to one country's spring landscape.

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.
