"I cani vedono in bianco e nero."

Translation: Dogs see in black and white.

not true. http://www.pedigree.com/All-Things-Dog/Article-Library/Do-Dogs-See-Only-In-Black-And-White-.aspx

I cani vedono in giallo, blu, e grigia. :)

EDIT: Fixed year-old typo "griga" instead of "grigia".

Blu? Isn't it azzurro?

[TheGandalf]

Duolingo has a strange idea of the Italian word for blue. In everyday speech, I'm fairly certain that people say "blu". It's the normal word for blue. But for some reason, Duolingo teaches you "azzuro" which is a type of blue, or sort of a fancier word for blue.

I'm sure Domenico Modugno will agree with you here, TheGandalf :) https://en.wikipedia.org/wiki/Volare_(song)

Would the word order not suggest that "Dogs see in white and black"?

[dmmaus]

Yes, but the order in English is always "black and white". To sound right in both languages, the three-word phrase "bianco e nero" effectively translates as a single chunk, into the three-word phrase "black and white". Applying the correct idiom, rather than word-for-word literal meaning, is part of learning the language.
