That's incorrect per the SC website regarding their identity/brand (posters besides me can debate whether it's a technicality or not). Cardinal is not Maroon - at least not in my color wheel.
From said website -

USC’s official colors are Pantone 201C and Pantone 123C.
These colors, designated as
USC Cardinal and USC Gold, are equal in importance in identifying the university. All printed materials, whether printed on coated or uncoated stock, should match color to the coated Pantone chips. The Pantone Matching System, or PMS, is the definitive international reference for selecting, specifying, matching and controlling ink colors. It is strongly recommended that drawdowns be requested with each print job to ensure that the PMS colors are accurate. The correct and consistent use of USC’s official colors helps reinforce the university’s identity.
Wikipedia also lists it as Cardinal and Gold as well -
