Ruminative Naval
Ruminative Naval (#585F7C) 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 (228°, 17%, 42%) places it in the muted 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 rūminātīvus, chewing-cud-like — adjectival suffix -ive. As a color modifier, ruminative implies a hushed-and-thoughtful-and-meditative quality where the hue carries the visual register of slow-and-careful-thoughtful interior-design-element. Sits at the hushed-and-still end of the grid, parallel to meditative and contemplative in usage.
Of the navy — the seagoing branch of a national military. Naval blue refers to the working color of warship paint and naval-shipyard equipment: a slightly muted very deep blue with the matte finish of marine enamel. Deeper than navy (the dress color), cooler than ocean, with the operational specificity of a color used to make a ship harder to spot at distance against North Atlantic water.

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 sits well within the sRGB cube. P3 and sRGB share the gray axis and most desaturated tones, so a P3 display renders this identically to an sRGB display.
