Brimming Pennant

#2d6fda
Notes

Brimming Pennant (#2D6FDA) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (217°, 70%, 52%) 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

Brimming
adjective

Old English brymme, brim / edge — present-participle of brim. As a color modifier, brimming implies a saturated-and-overflowing quality where the hue spills past the edge of its visual container with rich pigmentation. Sits at the bold-and-saturated end of the grid, parallel to replete and abundant.

Pennant
noun

A long triangular flag flown by warships — particularly the British Royal Navy commissioning pennant (a long blue-and-white streamer flown when a ship is in active commission). Pennant color refers to a fresh commissioning pennant: a saturated, slightly cool deep blue with the matte finish of dyed flag bunting.
