Composed Pennant

#374dbc
Notes

Composed Pennant (#374DBC) is a true blue 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 (230°, 55%, 48%) 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

Composed

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.
