Bevelled controls with light falling across them, fields as wells, solid windows, and glass kept for the chrome that floats over everything else. Warm graphite in dark, soft paper in light, one brand color driving both. Ships its own fonts (Instrument Sans, JetBrains Mono; OFL). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Niveus — Dark appearance
|
|
--------------------------------------------------------------------------
|
|
Values for the dark side of every semantic role, resolved through
|
|
light-dark() in tokens/color.css. Like the light appearance, almost nothing
|
|
here is a literal color — every role is derived from --nv-brand.
|
|
|
|
Dark Niveus is warm graphite, not the light theme inverted. Surfaces get
|
|
*lighter* as they rise and each step is large enough to see; shadows are
|
|
deep and every raised thing carries a near-black contact line, because on a
|
|
dark canvas a shadow alone has nothing left to darken. The bevel is what
|
|
carries depth here — a lit top edge, a shaded bottom one — and filled color
|
|
stays saturated: a vivid accent with a light label reads as a lit key, not
|
|
as a hole.

/* --- Accent -------------------------------------------------------------
|
|
The same derivation as light: a fill is pushed out of the mid-tones until
|
|
its label clears 4.5:1, so the brand keeps its full saturation and a light
|
|
label. Earlier Niveus lifted the dark accent into pastel to avoid neon;
|
|
with bevel and sheen doing the shaping, a saturated fill reads as a lit
|
|
key instead, and the pastel was what made the whole system feel washed
|
|
out. Only the accent *text* (links, subtle labels) moves up the ramp,
|
|
because text on a dark canvas needs the lightness that a fill does not. */
