Rabbi Rakefet Rothkoff reports that when he was in Lakewood, Rav Nosson Wachtfogel ZT”L would not wear a black hat. It is a yeridas hadoros that people can’t accept any colors other than black and white. Many men are to “frum” to wear adar blue suit. I can’t find the halacha against it- not in my mishnah brurah.
