Replete Starlight
Replete Starlight (#4B5DF2) is a true blue 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 (234°, 87%, 62%) 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
Latin replētus, filled — past-participle of replēre. As a color modifier, replete implies a saturated-and-fully-pigmented quality where the hue is completely loaded with its source pigment. Sits at the bold-and-saturated end of the grid, parallel to brimming and suffused in usage.
The integrated visible spectrum of the Milky Way's faint stars — about 500 times dimmer than full moonlight and richly blue-violet at high galactic-latitude viewing angles where dust extinction is minimized. Starlight color refers to the deep-blue night-sky background between the brightest stars on a moonless dark-site night: a saturated, slightly cool deep blue-violet with the optical complexity of integrated multi-stellar Rayleigh-scattered atmospheric light.

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.
