Fundamental Saltbush
Fundamental Saltbush (#5C4C52) is a deep magenta 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 (338°, 10%, 33%) places it in the muted band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary teal. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin fundāmentum, foundation — adjectival suffix -al. As a color modifier, fundamental implies a neutral-and-foundational-and-essential quality where the hue carries the visual register of Bauhaus-and-Mondrian-De-Stijl foundational-and-base-color theoretical-design fundamental-essential-element. Sits at the neutral-and-foundational end of the grid, parallel to foundational and essential in usage.
Australasian-and-North-American Atriplex genus — Amaranthaceae halophytic shrubs of arid-saline soils, with mid-cool-gray-green leaves with characteristic salt-vesicles on leaf-surface. Saltbush color refers to a Atriplex nummularia (old man saltbush) leaf-canopy on a South-Australian-Mallee grazing-paddock: a balanced cool gray with the matte finish of waxy-cuticular salt-secreting leaf-vesicles in semi-arid pasture conditions.

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.
