Luminous Cornsilk
Luminous Cornsilk (#C1C524) is a true yellow with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (61°, 69%, 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin lūminōsus, full of light — adjectival suffix -ous, derived from lūmen (light). As a color modifier, luminous implies a saturated-and-light-emitting quality where the hue carries internal-glow visual register. Sits at the bright-and-saturated end of the grid, parallel to radiant and resplendent in usage.
The fine pale-yellow filaments that emerge from the top of a corn ear — each silk is the style of a single ovary, and a single corn kernel won't develop without one being pollinated. The color is fresh cornsilk on an Iowa August ear: a soft, very pale yellow with the optical translucency of plant fiber. Lighter than straw, warmer than ivory, with the agricultural-summer association of a Midwestern field at silking.

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.
