Dogs see blue well, but that is not enough
Blue is one of the colours a dog tells apart best, but colour is not what makes him pee there. What matters most is where you put PIPPI: he chooses the spot himself, based on his surroundings, his habits and his instinct. Colour helps him see it, because dogs have two-colour vision: they see blue and yellow well. Red and green turn into shades of olive yellow that are hard to tell apart.


Through his eyes the red sofa turns olive yellow, while PIPPI stays the only blue thing. That is why blue helps a puppy recognise it, and an understated colour is less unsettling for an adult dog set in his ways.

To a dog, white stays white, ivory becomes a light cream and green a dull olive yellow, like the sofa in the photo: none of them stands out the way blue does. The choice for an adult dog set in his ways. And because white and ivory are light, you can see straight away when it needs a rinse.
