Brown

5 bricks, lightest to darkest: 3 clay, 2 natural stone. Lightness and undertone are measured on a photograph of each brick; colour on screen is a guide, and the sample is the reference.

5 bricks read as brown, 1 of them as a second colour. Rustic, tumbled, natural split. Working sizes: 380 × 100 × 50 mm, 390 × 105 × 45 mm, 210 × 100 × 65 mm.

L* is lightness on the CIELAB scale (0 black, 100 white), measured on a photograph of each brick. Undertone comes from the same measurement: cool, neutral or warm. Even or varied describes the colour difference between courses. Screens differ: reserve a sample, or see the bricks at the Richmond showroom, before you specify.
