Smooth Ryzhiy

#aa5521
Notes

Smooth Ryzhiy (#AA5521) is a true orange with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (23°, 67%, 40%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Smooth
adjective

Old English smōþ, level, polished — used as a color modifier since the seventeenth century for hues that read as continuous without texture or break. Smooth tan, smooth gray: moderate saturation combined with optical evenness. Sits in the crisp-bucket alongside even.

Ryzhiy
noun

The Russian word for red-orange or ginger — used for autumn foliage, fox fur, and the hair of redheads. Ryzhiy implies a slight blue-green undertone in shadow that distinguishes it from pure orange. The color refers to a ginger-cat coat in afternoon sun: a soft, slightly muted red-orange with the matte finish of mammalian fur. Drier than ember, warmer than rust.
