Bold Sleek Rose

#a21906
Notes

Bold Sleek Rose (#A21906) is a deep red with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (7°, 93%, 33%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Bold
adjective

Old English beald, brave, courageous — a quality word that crossed over to color in the late seventeenth century. Bold describes a color that asserts itself: high saturation combined with mid lightness, where the hue presents itself without compromise. Sits at the center of the bold-bucket grid, near strong and rich. Closer to a presence word than a pigment word.

Sleek
modifier

Middle Dutch sleeck, smooth. As a color modifier, sleek implies a smooth-and-streamlined quality, the visual register of Mid-Century-Modern-and-Streamline-Moderne-sleek hand-streamlined-and-aerodynamic-and-polished aluminum-and-chrome-and-bakelite Mid-Century-Modern-and-Streamline-Moderne sleek-and-streamlined surfaces under Mid-Century-Modern-and-Streamline-Moderne sleek-and-polished light. Sits at the modifier-and-texture end of the grid, parallel to gloss and shine 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.

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.
