Are Dogs Color Blind? Or Are They Just Fashionably Indifferent?

I’ll take the green one!

You’re walking your dog through the park, proudly rocking matching neon yellow outfits. You’re feeling cute. Your dog? They couldn’t care less. In fact, they seem to be actively avoiding eye contact with your lemon ensemble. Rude. But here’s the question: is it because they have no fashion sense… or because they literally can’t see it? Let’s chew on this: Are dogs color blind?

The Short Answer: Kind of, Yeah.

But don’t click away yet—there’s nuance here, and some surprisingly cool science. So, stick around, and I promise to make it worth your while (and probably throw in at least one poop joke).

What Does “Color Blind” Actually Mean?

When we say someone is color blind, we don’t mean they see the world like an old-time black-and-white movie (unless they’re a 1940s detective). Instead, it means they have a limited ability to perceive certain colors.

Humans, unless color blind, are typically trichromatic—we have three types of color receptors (called cones) in our eyes. These cones pick up red, green, and blue light. Mix those up in various ways and BAM, you’ve got yourself a full rainbow of visible color. Much like those old projection TVs of the 80’s that had the three different color lenses. OK, I’m really old, just Google it.

Dogs, on the other paw, are dichromatic. That means they only have two types of cones. Specifically, they can see blue and yellow, but not red or green. So, to a dog, that beautiful red rose? Just a murky brownish blob. Your lush green lawn? Also… a murky brownish blob. Honestly, the world probably looks a bit like an Instagram filter gone rogue.

So, No Red? That’s Ruff.

Nope, dogs can’t see red. And much like Sammy Hagar, I like red! (Yeah, I know, that old thing I mentioned earlier) In fact, red probably looks dark brown or grayish to them. Green also gets lost in translation. That bright green tennis ball you bought for your pup? To them, it looks almost exactly like the grass you threw it into.

Ever wonder why your dog struggles to find a ball you clearly just tossed? They’re not being dramatic or ignoring you (well, maybe a little). It’s because it literally disappeared into the background like a chameleon with a college degree in camouflage. I think that bright green tennis ball is for us humans so we can find it when our dogs can’t.

Canine Vision: Pros and Cons

Okay, so dogs got the short end of the rainbow. But before you start pity-partying for your pup, know this: they have visual superpowers that make up for it.

Here’s the breakdown:

Dogs might not ace an art class, but they’d be top of the charts in night spec ops. They have more rod cells in their retinas, which means they can see better in low light. They also detect movement way better than we do—which makes sense if your ancestors hunted by sniffing things and then pouncing at them.

The Fashion Question: Should You Stop Dressing Your Dog?

Hard no. Keep dressing your dog. Please.

Just maybe lean toward colors they can actually see. That fiery red bandana you love? To your dog, it’s probably just an oddly shaped shadow. But a bright blue raincoat? Stylish and visible. A vivid yellow harness? Now you’re speaking their language.

Of course, whether they want to be dressed at all is another story. Your dog absolutely loves it when you dress them. Or, more than likely, not. When my wife dresses our dogs, they look at me as if to say “help me!”

Can Dogs Be Actually Color Blind?

Technically, yes. Just like humans, dogs can have vision issues, including full or partial blindness and even rare cases of further color deficiencies. But the “standard model” of dog vision is dichromatic, and it’s pretty consistent across breeds.

So no, your dog isn’t color blind in the “something’s wrong” kind of way. They’re just naturally built to see the world differently. And in a lot of ways, their view makes total sense for survival in the wild. They don’t need to appreciate a sunset—they just need to see that squirrel bolt 50 yards away and ruin your afternoon picnic. Yes, I said squirrel! There goes my dog out the door.

Final Woof

To recap:

• Dogs aren’t totally color blind, but they can’t see the full spectrum like we can.
• They see mostly blues and yellows and everything else is like looking through muddy glasses.
• Their vision may be less colorful, but their night vision, motion detection, and ability to look adorably guilty after chewing your shoes? Top-tier.
• And yes, they still deserve fashion—even if they think every outfit is the same shade of “meh.”

So the next time your pup gives you side-eye while you wave a red toy like a maniac, just remember: they’re not being a jerk. They’re just wondering why you’re throwing invisible objects into the bushes again.

And that dog joke I mentioned earlier? Have you ever seen a dog playing poker and getting an all-hearts flush? Neither have they. (Because dogs can’t see red. OK, no need to explain this dumb joke)
