Vous voyez moins de 20 nuances de couleurs : Vous avez une vision dichromate, comme des chiens (et ouais, pas de bol). En gros, ‡a qui signifie que vous avez deux types de c“nes seulement. Vous ˆtes susceptible de porter du noir, du beige et du bleu. Sachez tout de mˆme que 25% de la population est dichromate. 

Vous voyez entre 20 et 32 ??nuances de couleur : Vous avez une vision trichromatique et disposez de trois types de c“nes (dans les zones violet / bleu, vert et rouge). Il semblerait que 50% de la population soit dans la mˆme situation que vous. 

Vous voyez entre 33 et 39 couleurs : Vous ˆtes un t‚trachromatique, comme des abeilles (MMaaayyyaaa !) qui disposent de quatre types de c“nes (dans les zones violet / bleu, vert, rouge et jaune). Vous ˆtes irrit‚ par le jaune et cette couleur sera introuvable dans votre garde-robe. 25% de la population a une vision t‚trachromatique. 

Vous voyez plus de 39 nuances de couleurs : Vous devez consulter un ophtalmo, puisqu?il n?y a que 39 bandes de couleurs diff‚rentes dans le test, et probablement 35 seulement sont correctement affich‚es par votre ‚cran
