Beaming Tuscan

#a3c61e
Notes

Beaming Tuscan (#A3C61E) 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 (73°, 74%, 45%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Beaming
adjective

The progressive participle of beam, to emit a directional light — used as a color word since the nineteenth century for hues that read as if focused and projecting. Beaming yellow, beaming pink: the implication is luminance combined with directionality. Sits at the bright-bucket center alongside radiant and glowing.

Tuscan
noun

Of Toscana, the central Italian region whose pale ochre stucco and warm terracotta roofs define a regional palette. The color Tuscan yellow refers to the limewash of Florentine and Sienese palazzo facades — a soft, slightly muted gold that's warmer than cream and lighter than honey. The pigment is the same iron-rich earth that gives sienna its name; mixed with lime, it ages to the patina of half a millennium.

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.
