"O vestido é colorido."

Translation: The dress is colorful.

Why not "the dress is coloured"?? It's in the translation.

[JCMcGee]

"the dress is colored" isn't a phrase that we'd use....it sounds clumsy to a native ear.

[AlonsoMond]

Maybe the sentence refers to emphasizing the "nice colors" and not that it's simply coloured. So you would say colorful and not colored

[Paulenrique]

That should be accepted..
