Straightforward Andalusite

#a66505
Notes

Straightforward Andalusite (#A66505) is a deep amber 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 (36°, 94%, 34%) places it in the highly saturated band at a dark 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Straightforward
adjective

English compound straight + forward — sharing root with German geradeaus. As a color modifier, straightforward implies a clear-and-direct-and-unencumbered quality where the hue carries the visual register of clear-aim-and-uncomplicated character. Sits at the crisp-and-honest end of the grid, parallel to candid and direct in usage.

Andalusite
noun

An aluminum silicate gem — pleochroic from yellow-brown to gold-green to red-brown depending on viewing angle. Mined principally in Brazil and Sri Lanka. The color refers to a faceted Brazilian andalusite seen along its strong axis: a soft, slightly muted warm gold-brown with the optical complexity of pleochroic stone.

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.
