If disregard the content of the artwork, it seems to be just a retro shoujo manga style. ( This statement holds true only for red and white. )
Red: Black, white, and red palette illustrations, with a thematic focus on Western subjects.
White: Black-and-white line art featuring extensive use of negative white space. This is arguably the artist's signature style, depicting the everyday life of the Japanese Showa era.
Gray: Monochrome illustrations utilizing a heavy gray scale. This style leans more toward realism.
