1 Answer

Answer :

(1) Blue Explanation: Complementary colours are pairs of colours that are of "opposite" hue in some colour model. In colour theory, two colours are called complementary if, when mixed in the proper proportion, they produce a neutral colour (grey, white, or black). In roughly-perceptual colour models, the neutral colours (white, grey, and black) lie along a central axis.
