Oh, the ever famous canary yellow. The first time that I ever realized that this was a color to consider was in grade school. Flyers and other important papers that my teachers handed me were always in the ‘canary yellow’ 8-1/2x 11″ paper. Oh, those were the simplest of times, the best of times.
Yellow is the color evoked by light that stimulates both the L and M (long and medium wavelength) cone cells of the retina about equally, with no significant stimulation of the S (short-wavelength) cone cells. Light with a wavelength of 570–580 nm is yellow, as is light with a suitable mixture of red and green. Yellow’s traditional RYB complementary color is purple, violet, or indigo, while its colorimetrically defined complementary color in both RGB and CMYK color spaces is blue.
The Yellow Canary (Serinus flaviventris) is a small passerine bird in the finch family. It is a resident breeder in much of the western and central regions of southern Africa and has been introduced to Ascension and St Helena islands.
