"Cartea este colorată."

Translation: The book is colored.

[ThomasHayc]

"The book is colourful" is not acceptable?

[Lng52-._]

I believe it's acceptable. Just report to DL.

[TomRuffles]

But in English coloured and colourful mean different things - coloured just means it is in colours, colourful in pictures would mean bright/striking colours, and in words is a euphemism for swear words ('he used colourful language').

[LABv7L1N]

We'd usually use 'coloured' as in: 'The pictures in the colouring book are coloured in' or 'the book is coloured yellow, red and blue'.
