salyu x salyu had a new song out? Titled Color Magic (カラーマジック, or the KATAKANA~ pronunciation KARA~ MAJIKKU — you know Katakana baffles me), it was included in NHK’s Design Ah (デザインあ), but you know it would be the perfect companion song to 6COLORS.
The song (if my Japanese is correct) will be included in the soundtrack of the show to be released on January 23rd.
They also have an awesome (interactive) song titled Ah’s Song (「あ」のうた).
