Mighty Daylily
Mighty Daylily (#CE641D) 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 (24°, 75%, 46%) 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
Old English mihtig, strong — adjectival suffix -y, sharing root with German mächtig. As a color modifier, mighty implies a saturated-and-strong-presence quality, where the hue commands visual attention through pure pigmentation strength. Sits at the bold-and-saturated end of the grid, parallel to forceful and commanding in tone.
The genus Hemerocallis — day-beauty in Greek — perennial lily-relatives whose individual flowers bloom for a single day before wilting. The color refers to a fresh orange daylily H. fulva on a roadside: a saturated, slightly red orange with the satin finish of trumpet-shaped flower. Brighter than tangerine, with the ephemeral weight of a flower whose bloom lasts hours.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
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.
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.
