The colour orange occurs between red and yellow in the visible spectrum at a wavelength of about 585 – 620 nm, and has a hue of 30° in HSV colour space. The complementary colour of orange is azure, a slightly greenish blue. With pigments such as paints or inks, a mixture of the subtractive primary colours in the proportion of 75% yellow and 25% magenta produce the secondary colour orange. Orange pigments are largely in the ochre or cadmium families, and absorb mostly blue light.
