Hospitable Lepidolite
Hospitable Lepidolite (#4C59A8) is a true blue with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (232°, 38%, 48%) 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
Latin hospitābilis, of-the-host — adjectival suffix -able. As a color modifier, hospitable implies a clear-and-cordial-and-welcoming quality where the hue carries the visual register of Bed-and-Breakfast and country-inn warm-cordial-host atmosphere. Sits at the crisp-and-cheerful end of the grid, parallel to welcoming and inviting in usage.
Lithium-bearing potassium mica — pink-to-violet from manganese substitution, sourced from Newry, Maine, and Tanco, Manitoba. The mineral was the Soviet space program's primary lithium source. Lepidolite color refers to a Newry lepidolite booklet on its native pegmatite matrix: a saturated, slightly cool deep blue-violet with the silvery finish of foliated mica with lithium-substitution-induced violet coloration in the cleavage planes.

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.
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.
