Translation:Only yellow and brown refrigerators are left.
You can. It is accepted. As always, If a sentence want accepted, you must report the complete sentence. Preferably by pressing "My answer should be accepted" so that we can see exactly what you typed.
This is a GUESS, but I'll offer it anyway... "There are" in English seems to come most often from "to jsou" in Czech. Since there's no "to jsou" in this sentence, that may be why your answer was not accepted. Or, it may just be a "missing" translation, in which case you might Report it if you get this one again.
UPDATE - - - - - This is now an accepted translation. Thanks!
