Dogs do in fact see "in color", as shown by the fact that a dog's eye contains both rods (which we associate with B/W vision) and cones (which differentiate between colors).


While humans' cones are attached to neurons that react to light at 435nm, 545nm and 570nm, a dog's cones react at 429nm and 555nm.


This means that a dog sees somewhat as does a human with red-green color blindness.


This means, for instance, that what a human perceives as red, a dog probably perceives as green, and what a human perceives as yellow, a dog sees as a neutral color -- gray.

    • I am trying to find out about people's experiences of the 4+ and 7+ assessments. I am a teacher and have a wealth of experience tutoring for theses assessments (including my own son), but it's always good to keep on top of things as they always make tweaks to them. TIA!

    • "You have no idea why"   To be fair Sue, it's blindingly obvious to anyone who has a conversation with anyone who isn't a Corbyn supporter. And even some who liked Corbyn (like me initially) found him somewhat flaky even at his most popular But let's say you are right and I have NO idea why anybody might not vote for him. They still didn't vote for him. He lost two elections. The second one badly (and strongly predicted but the stubborn old goat wouldn't budge so we we were stuck with Johnson and another 3 million PMs in the 5 years that followed) So even with ZERO evidence, we have our eyes and ears and brains But we do have evidence   https://yougov.co.uk/politics/articles/27022-their-own-words-why-voters-abandoned-labour
    • As I said, it was my understanding. I worded it very carefully. I didn't/don't know for sure, so clearly not a fact. And hardly an "opinion", which is something completely different. You have no idea what reason anybody might have had for not voting for him (unless you can point to some opinion poll results which actually asked people?)
