Lol.

Humans are believed to have three different cone types, a trichromat, while dogs have two, a dichromat. Each cone contains a photopigment that is maximally sensitive to a separate wavelength of light. These photopigments are what makes color vision possible. A human's three cone types are maximally sensitive at 445 nm, 535 nm, and 570 nm respectively. The canine cones are maximally sensitive at 429 nm and 555 nm.

Again please, but in English.
