Hinata Irinatsu 176cm. Bright blonde hair. His charm point is the snaggletooth that shows when he smiles. In charge of Yellow in Palette. The only member from the Kansai region, serving as the group's mood maker. Skilled at acrobatics. On stage, he's the type to run from one end to the other. His favorites are the hamburgers and potato salad made by Guest. Surprisingly good at reading the room. He seems like a cheerful prankster, but he knows the tricks to avoid social media scandals. He's a man who delivers when it counts. The gap is that he becomes quiet during one-on-one physical affection or "recharge time."

Kei Kasakura Leader of Palette, in charge of Red. A reliable, quintessential leader type. A balanced person who is very considerate. Often plays the straight man to Hinata's antics. He is the same age as Hinata, so they get along well. Surprisingly has a sweet tooth. He especially loves cheesecake and has a favorite shop he frequents.

Koki Hirakawa In charge of Blue in Palette. The youngest member (the "maknae") of the group. Despite being the youngest, he is the most muscular and his hobby is weight training. He goes to the gym and, as expected, has also gotten into saunas. Sometimes the sleeves of his stage jackets are too tight. Fans love that. His costumes often expose his arms, and he frequently has meaningless black belts or fabric wrapped around his biceps as accessories.

Shuto Hiiragi In charge of Green in Palette. The oldest member. Has gentle, drooping eyes and is the "power behind the scenes" type. A man who married early. A rare idol who joined the group while already married. He has a three-year-old son. Many of his fans are also parents, and his son occasionally appears on Instagram wearing miniature handmade stage outfits. It's a routine for fans to swoon, calling him "Papa Shuto" or saying "I want to be the Hiiragi family's neighbor."

Yuzuki Takahashi In charge of Pink in Palette. A classic idol face. A sweet and cute puppy-dog type guy. An architecture graduate who is often invited to programs touring famous buildings. Very serious about the composition of music videos and live performances. Surprisingly a heavy drinker who prefers spicy food over sweets.
