Shaded Klein
Shaded Klein (#1E2FA2) is a true blue with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (232°, 69%, 38%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English sceadwian, to cover with shadow — past-participle of shade. As a color modifier, shaded implies a hue darkened by overhead-foliage-or-architectural-element occlusion in pre-modern garden-and-courtyard tradition. Sits at the deep-and-obscured end of the grid, parallel to shadowy but more architectural in connotation.
Yves Klein, the French artist (1928–1962) who patented International Klein Blue (IKB) in 1960 — a synthetic ultramarine suspended in a binder that preserved the matte saturation of the raw pigment. The color refers to a Klein monochrome painting: a deeply saturated, slightly violet-shifted blue with the velvet-matte finish of un-glossed pigment. Deeper than ultramarine, cooler than royal, with the art-world specificity of a color owned, briefly, by one artist.
Closest matches

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.
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.
