Established Sakura

#b11005
Notes

Established Sakura (#B11005) is a true 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 (4°, 95%, 36%) places it in the highly saturated band at a mid 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

Established
adjective

Latin stabilīre, to make stable — past-participle of establish. As a color modifier, established implies a saturated-and-rooted quality where the hue carries the weight of long-standing visual presence. Sits at the bold-and-firm end of the grid, parallel to steadfast and anchored in usage.

Sakura
noun

The flowering cherry — Prunus serrulata — and the unifying spring color of Japanese aesthetic life. The color refers to a somei-yoshino cherry in full bloom: a soft, slightly cool pale red-pink with the matte finish of five-petaled bloom. Lighter than rose, cooler than coral, with the ephemeral weight of a flower whose two-week bloom defines an entire season's poetry.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
