Weighty Glaucium

#274cd7
Notes

Weighty Glaucium (#274CD7) is a true blue with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (227°, 69%, 50%) 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

Weighty
adjective

Old English wegan, to weigh — adjectival suffix -y. As a color modifier, weighty implies a saturated-and-heavy-and-imposing quality where the hue carries visual mass and gravitational presence. Sits at the bold-and-weighty end of the grid, parallel to substantial and hefty in usage.

Glaucium
noun

The genus Glauciumhorned poppy, Mediterranean coastal-dune annuals with silver-blue foliage and yellow or orange flowers. The genus name traces to the same Greek glaukos as glauque (gray-blue-green). The color refers to mature Glaucium flavum foliage: a soft, slightly cool deep silver-blue with the matte finish of waxy-cuticled coastal-dune leaf.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
