Tenacious Brine Rose

#c01f42
Notes

Tenacious Brine Rose (#C01F42) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (347°, 72%, 44%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Tenacious
adjective

Latin tenāx, holding-fast — adjectival suffix -ous. As a color modifier, tenacious implies a saturated-and-clinging quality where the hue grips its substrate with stubborn pigmentation. Sits at the bold-and-resilient end of the grid, parallel to unyielding and adamant in usage.

Brine
modifier

Old English brȳne, salt-water-or-pickle-brine. As a color modifier, brine implies a salt-water-and-pickle-and-tide-pool quality, the visual register of Atlantic-tide-pool-and-pickling-brine hand-salt-water-and-pickle-and-tide-pool Atlantic-tide-pool-and-pickling-brine-and-Cornish-rock-pool brine-and-salt-water-and-pickle surfaces under Atlantic-tide-pool-and-pickling-brine-and-Cornish-rock-pool Lizard-Point-and-North-Cornish-coast salt-tide-pool-light. Sits at the modifier-and-weather end of the grid, parallel to floe and torrent in usage.

Rose
noun

The Latin rosa, the Greek rhodon, the Persian gul — every European language has a different name for the same flower and the same color. Rose covers the spectrum from blush to fuchsia depending on the cultivar, but in pigment shorthand it means a cool, slightly bluish red — the inside of a damask petal, the dye that washes out of madder root.
