"Αυτό το εστιατόριο είναι πορτοκαλί."

Translation: This restaurant is orange.

[Dmatafonov]

why sometimes its said like εχει πορτοκαλι χρωμα but sometimes ειναι πορτοκαλι? Which is better?

[Dimitra956826]

These two mean the exact the same thing. You can use whichever one you like, both in spoken and written Greek. I guess both of them are mentioned here on Duo just to show the variety in sentence structure ^.^

[GiannisPap2]

Είναι πορτοκαλί is used more often
