Colour blocking
Placing large, flat areas of strong, contrasting colour side by side.
Also: colour block
In colour blocking, solid colours meet at clean edges with no pattern or blending between them: a pink top with red trousers, a wall half yellow and half blue. The idea owes much to the Dutch painter Piet Mondrian, whose grids of red, yellow and blue inspired a famous dress by Yves Saint Laurent in 1965. It appears in fashion, interiors, packaging and architecture. Many traditional forms did it long before the name existed, among them Kanchipuram saris with contrasting borders and the painted houses of the Ndebele.
