Rich Nuthatch

#118ae1
Notes

Rich Nuthatch (#118AE1) 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 (205°, 86%, 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Rich
adjective

Old French riche, wealthy, abundant — applied to color since the medieval period for hues that read as plentiful in pigment. Rich red, rich brown: the implication is depth combined with saturation, a color that gives the eye more to absorb. Sits at the saturated mid-light corner of the engine's grid, slightly warmer than bold and deeper than vivid.

Nuthatch
noun

The family Sittidae — small woodpecker-like songbirds — particularly Sitta canadensis (red-breasted nuthatch) and S. carolinensis (white-breasted nuthatch), whose blue-gray backs distinguish them from other woodland birds. The color refers to a male white-breasted nuthatch's back: a soft, slightly cool deep blue-gray.
