On the colour wheel, the opposite of brown is dark blue. Brown is only included on colour wheels with more colours and a greater level of detail.
Brown is a tertiary colour, which is created by mixing two secondary colours or one secondary colour and one main colour. Different mixtures of oranges, reds, and yellows produce the colour brown. Depending on the exact shade of brown, its opposite on the colour wheel may be a deep violet or a deep blue-green. In general, colours that are opposite one another on the colour wheel are complimentary, meaning they pair nicely in decor, art, and fashion.
