We set up key colors for each of the characters […] For example, Jaeyoung has yellow, red, and orange; those sort of warmer colors and lighting that are incorporated in the framing of his scenes and spaces. And on the other hand, for Sangwoo, he has cold and stiff colors like white, blue, and black in his framing and spaces. So like in Sangwoo’s room, blue light is constantly coming in through his window, and we included a white desk lamp for lighting design. As for Jaeyoung, in his studio he has a pink neon light and orange stand lamps.
When the two of them have some sort of emotional exchange and fall for each other, the other person’s colors and lights will permeate into their individual framings. For example, in episode 4, the moment that Jaeyoung sees Sangwoo with wet hair, there’s a slight blue light coming in from behind him. And on the other side, there’s an orange streetlamp light coming in through the window behind Sangwoo. And in the scene where they call each other in episode 6, Jaeyoung’s taking the call in a bar; there’s blue light that casts on his face. That bar space originally had red lighting, but our lighting director changed it all to blue. On the other hand, for Sangwoo, he’s next to his window with the streetlight, and orange light casts on his face.
Emotionally, the two of them are dyeing one another [with their own colors].
