Inviting Yogyakarta
Inviting Yogyakarta (#23589F) is a true azure 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 (214°, 64%, 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin invītāre, to invite — present-participle of invite. As a color modifier, inviting implies a clear-and-cordial-and-encouraging quality where the hue carries the visual register of warm-inviting-and-encouraging entrance-foyer color tone. Sits at the crisp-and-cheerful end of the grid, parallel to welcoming and hospitable in usage.
The Indonesian Javanese cultural capital — and the deep blue of batik textiles produced in the Kraton (royal palace) and Imogiri royal-cemetery workshops. Yogyakarta color refers to a batik tulis deep-blue silk: a saturated, slightly cool deep blue with the satin finish of indigo-and-soga (resist-dye) batik.

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.
