On the April 10 installment of�MBC Everyone's 'Showtime - Burning the B2ST', Junhyung admitted for the first time that he had color weakness, which is a variation of color blindness in that colors appear less distinctive for him than it would for others.

Kikwang said, "There was a time Sunmi came out with pink hair," and a fun time ensued as the other members chatted about this when suddenly Junhyung said seriously, "Don't talk about colors."

Surprised, everyone asked him why and Junhyung broke into laughter and said, "Because I have color weakness."
