The brief was horizontal-band symmetry for Mumbai Metro — not sun-moon celestial arch, not forest-scatter, and absolutely no tarpa spiral smuggled in because the subject is urban transit. Metro Mumbai is a translation problem: how does an elevated train with open-door boarding, cable-stayed bridge silhouette, and street-level auto-bicycle-car chaos read inside Warli monochrome without looking like a transport brochure pasted on geru? Horizontal-band was the layout fix — classical Warli stacks narrative registers; here skyline and Sea Link occupy the upper band, the metro train is the oversized horizontal hero centre, platform and stairs hold the middle commute layer, and street traffic anchors the lower band like a village path scene scaled to Bandra. What we refused: perspective depth, MMRCL branding, multicolor train livery, concentric dance rings. What we kept legible: triangle-window passengers inside carriages, figures at open doors, pillar-supported elevated track, cable pylon with stay lines, umbrella walker on upper walkway, auto and sedan at street level. Light-mid density keeps ochre visible between bands — the metro span needs breathing room to read as hero.
