At the live performance comeback event on April 21, IU talked about her collaboration with G-Dragon and revealed that she was always a big fan of the idol star.�

She also stated, "I asked for a lot of advice when I was writing the lyrics to 'Palette'. Featuring (G-Dragon) wasn't in my mind. I just asked him for a lot of advice while I was working on the track and later on, I thought it would be good to have rap part so I asked him."

IU continued, "He already had a good understanding of the track's tone since I already discussed it with him a lot. His voice goes along well so I asked and fortunately, he happily accepted."
