Chemical Blue is a manga-influenced comic by Irina Richards. It originally started as a webcomic in 2008; Richards joined the Sweatdrop Studios collective the following year, and began publishing printed editions of the comic under the Sweatdrop label. In 2010 the first four issues were collected in a single volume.
Chemical Blue revolves around Amber Kayar, a college student who is interested in chemistry. The comic tells the story of her life from the first day of college onwards, focusing on her relationships with her friends Leanne, Shawn and Kelly. Serving as an antagonist is Ellen, Amber's thoroughly unpleasant roommate.
