I know LOTS of people still like and use the braided line with the red/blue ends and I myself, have totes full of lines like that. But these days, I don't know, I guess it just strikes me as very 80s on the look, plus the stuff is heavy and harder to work with. Especially if you have a car with LOTS of plumbing, that look is just very "busy" to me now. While I still do at times use a colored fitting now, it is usually black ends on black hose
