Dense Surkh

#b33874
Notes

Dense Surkh (#B33874) is a true magenta 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 (331°, 52%, 46%) 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

Dense
adjective

Latin dēnsus, thick / crowded — sharing root with English condense. As a color modifier, dense implies a saturated-and-tightly-packed quality where the hue carries maximum pigmentation per visual unit-of-area. Sits at the bold-and-saturated end of the grid, parallel to thick and concentrated in usage.

Surkh
noun

The Persian word for red in its most saturated, formal sense — used in Iranian poetry and miniature painting for the ribbons of court banners, the robes of warriors, and the high-saturation reds of Safavid tile. The color refers to a surkh-dyed Persian carpet: a saturated, slightly cool deep red with the matte finish of plant-dye-on-wool. Deeper than crimson, warmer than burgundy.

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.
