Russian researcher team proved that it turns out dogs can distinguish colors.
These findings break the assumption that most scientists believe, that
the animals are often referred to as human's best friend can only see on
black and white.

For
comparison, on the human since the beginning of the life stage equipped
with three cones that allow we could see for the premiere three colors
namely red, blue, and green. Similarly, as stated in Phys, on Friday,
June 26, 2013.
To find out more details, In the first "training" stage of the experiment, researchers paired two papers that differed in both qualities—dark yellow went with light blue; light yellow went with dark blue. These markers were placed in front of feedboxes that contained raw meat—but crucially, only one of the boxes was unlocked. Over a series of trials the dogs learned to associate the meat with the one color it was consistently marked with. To reinforce the lesson, dogs each went through 90 total trials.
Then the researchers changed things around. Dogs that had been trained to associate dark yellow with a reward were now given two novel options: light yellow and dark blue. Their first choice of feedbox thus indicated whether the most salient quality, for them, was the color (yellow) or the brightness (dark) of the original marker.
Over a series of 10 tests, the dogs went for color matches more than 70 percent of the time. And for half of the dogs, color was what they based their decision on every single time. Thus they’d clearly memorized the color associated with the treat, not its brightness. The results are published in the Proceedings of the Royal Society B. Thus, the animals that have two cones apparently able to distinguish the colors and do not rule out the possibility that they can respond in a way that has not been previously studied. *** [EKA | FROM VARIOUS SOURCES | DISCOVER | JAM | PIKIRAN RAKYAT 01082013]
