Plain Russet

#903037
Notes

Plain Russet (#903037) is a true red 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 (356°, 50%, 38%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Plain
adjective

Latin planus, flat, level — used as a color modifier since the medieval period for hues that read as undecorated and direct. Plain white, plain blue: moderate saturation, no shift, no surface effect. Sits in the crisp-bucket center, with the implication of restraint rather than absence.

Russet
noun

From the Old French rousset, reddish-brown. A medieval term for the coarse, undyed wool of peasant cloth — the natural red-brown of the local fleece. The color now refers to autumn foliage, the skin of a russet potato, the rust-stained sandstone of the American southwest. Earthier than rust, drier than mahogany; the red of October.

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.
