Color Theory (stylized in all lowercase) is the second studio album by American indie rock singer-songwriter Soccer Mommy, released on February 28, 2020, by Loma Vista Recordings.

[1][2] Described by AllMusic as "grunge-lite," and by NME as "an account of personal pain set to warm lo-fi pop," Sophie Allison herself has described the sound on Color Theory as "the music of my childhood distressed.

Additionally, Allison used floppy disk samples, drum machines, and sound effects on the album, and employed unorthodox instruments such as the Mellotron and Wurlitzer.

"[22] Michael Hann of The Guardian wrote "Sophie Allison’s second album deals with ill-health and despair, but you would hardly know it from the fantastic arrangements and tunes.

[24] AllMusic wrote, "Though the songs here aren't quite as immediately infectious as Clean, its combination of deceptively warm surfaces, alluring melodies, and subtly distorted textures reward repeat listens with that sense of discovery.
