Reserved Spa
Reserved Spa (#46665F) is a deep teal 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 (167°, 19%, 34%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
The past participle of reserve, to hold back — used as a color modifier since the seventeenth century for hues that read as restrained and undemanding. Reserved beige, reserved navy: low-to-moderate saturation combined with optical restraint. Sits at the hushed-bucket alongside quiet and modest.
A mineral-spring resort — named for the Belgian town of Spa whose iron-rich springs have drawn visitors since the sixteenth century. Spa color refers to a thermal spring pool at Saturnia in Tuscany: a saturated, slightly cool deep blue-green with the optical complexity of mineral-saturated 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.
