Forthright Neel

#0664ef
Notes

Forthright Neel (#0664EF) is a true azure 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 (216°, 95%, 48%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Forthright
adjective

Old English forð-riht, straight ahead, direct. Used as a color modifier in Anglo-Saxon-revival contexts for hues that read as honest and unguarded. Forthright red, forthright blue: the saturation is full, the hue is presented without ornamentation or qualification. Sits in the bold-bucket center alongside frank and direct.

Neel
noun

The Hindi-Urdu word for indigo — borrowed from the Sanskrit nīla (dark blue) — and the source of the English aniline and many South Asian textile-dye terms. The color refers to a freshly neel-dyed Indian cotton: a saturated, slightly cool deep blue with the matte finish of plant-and-mordant dye. The South Asian cousin of indigo.

Wide gamut

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.
