• Jensen is a goth  at least, he dresses all in black and whatnot
• Jensen is also an artist, and is doing a mural as a school project
• Jared and he are in an established relationship
• Jared is also an artist, specifically a photographer
• He is Jensen's complete opposite in that he dresses ultra cheery - sparkles and bright colours and pink

 There's a sequel where the boys are at college, and at first all of Jensen's new friends think Jared is a twink because of the way he dresses, and then Jared sort of without intending to - awes them all by how astute and articulate he is, esp. about art. The sequel has an art show in it, too, with Jensen doing some pieces for it.
