Dog vision simulator
Dogs don't see in black and white — they see a world of blues and yellows. Upload a photo to see it the way your dog does, find out whether your dog can spot that new toy on the lawn, and check how any palette looks in dog vision. Everything runs privately in your browser.
Drop a photo to see it through your dog's eyes
How to use the dog vision simulator
- Drop in a photo — a toy on the grass, your living room, your dog's favorite spot.
- Compare what you see with what your dog sees, and add eyesight blur for realism.
- Use the toy tester to pick a toy color your dog can actually find.
- Paste any HEX codes to see a palette in dog vision.
How do dogs see color?
Dogs are dichromats: their eyes have two kinds of color-sensing cones instead of our three, tuned to blue-violet and yellow-green light. That means blues and yellows stand out, while reds, oranges and greens collapse into similar brownish, olive or gray tones. It's very similar to deuteranopia, a common form of red-green color blindness in people (Neitz, Geist & Jacobs, 1989).
Why do dogs lose red and orange toys?
A bright red or orange toy on green grass is high-contrast to us, but for a dog both colors fall on the same yellowish-brown axis, so the toy blends in. Blue and yellow toys are far easier for dogs to spot on grass — the toy tester above shows the difference.
Is my dog's eyesight blurry?
A little. Dogs' visual acuity is estimated at around 20/75, so they see fine detail less sharply than most people — the blur slider approximates this. In exchange they're better at seeing motion and in low light.
Frequently asked questions
Are dogs color blind?
Not completely. Dogs see color, but only along a blue–yellow range, similar to people with red-green color blindness.
What color toys can dogs see best?
Blue and yellow. They contrast strongly with grass and most floors in dog vision, while red, orange and green toys tend to blend in.
What colors can't dogs see?
Dogs can't tell red from green; both look like muted yellowish browns or grays to them.
Is this an exact simulation?
It's an approximation based on research into canine color vision; individual dogs and lighting vary.
