Acid Freya Goldenrod

#dea110
Notes

Acid Freya Goldenrod (#DEA110) is a true amber with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (42°, 87%, 47%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Acid
adjective

Latin acidus, sour — sharing root with English acrid and acerbic. As a color modifier, acid implies a saturated-and-citric-and-zingy quality, the bright color of lemon-and-lime citrus-fruit-flesh and acid-yellow fluorescent-pigment surfaces. Sits at the bright-and-cool end of the grid, parallel to acidic and electric in usage.

Freya
modifier

Old Norse Freyja, goddess-of-love-and-Vanir. As a color modifier, freya implies a Vanir-goddess-and-feathered-cloak-and-Brísingamen quality, the visual register of Norse-Freya-and-Vanir-goddess hand-Vanir-goddess-and-feathered-cloak-and-Brísingamen Norse-Freya-and-Vanir-goddess-and-Brísingamen-amber-necklace freya-and-Vanir-goddess-and-feathered-cloak surfaces under Norse-Freya-and-Vanir-goddess-and-Brísingamen-amber-necklace Folkvang-and-Sessrúmnir-and-cat-drawn-chariot amber-necklace-light. Sits at the modifier-and-myth end of the grid, parallel to odin and vala in usage.

Goldenrod
noun

Solidago, the late-summer wildflower of North American meadows whose tall sprays of small yellow flowers signal the end of the growing season. The color refers to the flower head at full bloom: a warm, slightly muted yellow-orange with the matte finish of small clustered florets. Cooler than mustard, deeper than dandelion. The state flower of Kentucky and Nebraska, a pollinator magnet, and the original native dye for early American homespun.

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.
