Lavish Sundown

#6645bc
Notes

Lavish Sundown (#6645BC) is a true indigo 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 (257°, 47%, 50%) places it in the balanced 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Lavish
adjective

Old French lavasse, downpour — sharing root with laver (to wash). As a color modifier, lavish implies a saturated-and-extravagant quality where the hue spills over its visual boundaries with luxurious pigmentation. Sits at the bold-and-saturated end of the grid, parallel to opulent and sumptuous in usage.

Sundown
noun

English compound for the moment of sunset's last upper-limb contact with the horizon — the brief window when the eastern anti-solar sky is at its deepest Belt of Venus indigo before nightfall. Sundown color refers to a clear-sky eastern anti-solar horizon at sundown: a saturated, slightly cool deep blue-violet with the optical complexity of Rayleigh-scattered Belt of Venus light against the rising Earth shadow.

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.
