Yes, that's correct, at least to our eyes. Perhaps more correct to say that the sun shines brightest in frequencies that we see as yellow if we treat it as a perfect blackbody (so that its "colour" is only determined by its temperature). In reality, however, it's not a perfect blackbody, and actually would shine brightest in green - or even infrared, depending on how you measure it. The colour of stars is a surprisingly complicated topic!
