Color Chart

Color Chart (カラーチャート) is a unit from Hinatazaka46. The unit appeared the first time on Hinatazaka46's 6th Single, tteka. The members unofficially called themselves Saitama Trio (埼玉三人組) until their final name was revealed, as all three grew up in Saitama Prefecture.

The name "Color Chart" derives from the official PR slogan of Saitama Prefecture, "Sai no Kuni" (彩の国), meaning "Colorful Country".
