No accent colour. The product is the palette. Dark is the default; “I Wanna White” flips the whole site to a light studio on #EAEAEA, the same grey the white tee was shot on. The switch is instant. Click any colour to copy it.

07 · ImageryDeep blacks, studio grey

  1. 01

    The shirt is the hero. Photoreal, alone, centred, lit from the top-left. Never a flat mock-up.

  2. 02

    Keep the blacks deep. Never lift them to grey. Detail lives in the rim light.

  3. 03

    White is its own shoot. Shot natively on #EAEAEA, never recoloured from black.

  4. 04

    Cotton bolls, not petals. The fibre is the only prop.

  5. 05

    One muse, deadpan. Same styling every time: black beanie, wide trousers, a timestamp.
