A design language that studies each record as a luminous pigment bloom on ink-green ground — saturated watercolour glowing through the dark, traced in pale herbarium ink.
Where most dark interfaces fall to grey, Sumiha lets saturated jade, amber, and rose washes pool behind content — each module reading as a watercolour bloom on archival ink-ground, annotated with the discipline of a specimen sheet.
Translucent radial washes carry the accent hue, recolouring instantly when the palette is swapped.
Serif titles, uppercase mono codes, and hairline rules read every module like a herbarium plate.
Pale ink on deep ground keeps high legibility while the washes do the singing.
Bold confident watercolour — saturated translucent pigment fields, fine ink linework, crisp feathered wet-edges — set against the language's own nocturnal ground rather than white paper.
Every screen carries the same ink-ground calm, the same glowing washes, the same annotation discipline.
