Tranquil Maelstrom
Tranquil Maelstrom (#1A1407) is a deep amber with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (41°, 58%, 6%) places it in the balanced 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin tranquillus, calm, still — used as a color modifier since the sixteenth century for hues that read as deeply restful, with the slight institutional weight of a word that names its own kind of room and prescribes a specific kind of light. Tranquil gray, tranquil cream: low saturation combined with optical stillness. Sits at the neutral-bucket alongside calm and quiet.
Norwegian Malstrøm, grinding-stream — the deep-cool-gray Saltstraumen tidal whirlpool off Norway's Bodø coast, the strongest tidal current in the world. Maelstrom color refers to a Saltstraumen whirlpool surface at peak tidal flow: a dark cool-gray with the optical complexity of high-velocity tidal-current-mixed Norwegian-coast saltwater against the deep Salten-fjord marine-stratified water column.

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.
