Dark blue is brown’s opposite on the colour wheel. Only more comprehensive colour wheels that include several colours of colour and include brown.
Because it is a tertiary colour, brown is created by mixing two secondary colours or one secondary colour and one main colour. Orange, red, and yellow are used in a variety of ways to generate brown.
The colour wheel opposite of a particular brown shade may also be a deep violet or a deep blue-green shade, depending on the shade of the brown. On the colour wheel, opposite colours are typically complimentary, which means they look good together in design, art, or clothing.
