Although “It is right” may mean «правильно», it is mostly used before an infinitive (e.g. “I don’t think it is right to do that”). In the given sentence, «Правильно» corresponds to “[That’s] right”. When “right” modifies an adverb as in “it is right there” or “we’ll go there right after the concert”, the word “right” is translated into Russian as «прямо».
