Firm Sari Crimson

#ad1a1e
Notes

Firm Sari Crimson (#AD1A1E) is a true red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (358°, 74%, 39%) 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

Firm
adjective

Latin firmus, strong / stable — sharing root with English farm (originally a fixed-yearly-rental). As a color modifier, firm implies a saturated-and-resolute quality where the hue holds its visual position without wavering. Sits at the bold-and-firm end of the grid, parallel to steadfast and unwavering in usage.

Sari
modifier

Sanskrit śāṭī, long-draped-cloth. As a color modifier, sari implies an Indian-sari-and-Banarasi-and-Kanjeevaram-silk quality, the visual register of Banarasi-and-Kanjeevaram-sari hand-Indian-sari-and-Banarasi-and-Kanjeevaram-silk Banarasi-and-Kanjeevaram-sari-and-Mysore-and-Bengal-cotton sari-and-Indian-sari surfaces under Banarasi-and-Kanjeevaram-sari-and-Mysore-and-Bengal-cotton Varanasi-and-Kanjeevaram-and-Mysore-loom Indian-loom-light. Sits at the modifier-and-textile end of the grid, parallel to kimono and haori in usage.

Crimson
noun

From the Old Spanish cremesin, itself from the Arabic qirmiz — the kermes scale insect, dried and ground into a brilliant carmine dye prized in the medieval Mediterranean. For centuries the most expensive red on a draper's shelf, reserved for cardinals, kings, and the cloth that gave English the word crimson. Cooler than scarlet, deeper than rose; the color of pomegranate seeds and a serious occasion.

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.
