The University of California's new logo isn't getting high marks from some students, employees and alumni.

More than 45,000 people have signed an online petition calling on the university to scrap the recently designed icon, which features a yellow, faded "C" inside a blue, book-shaped "U."

Online critics are calling it cheap, corporate and unworthy of a great university.

UC officials say the university developed the new logo because its traditional "Let there be light" seal had too many details to reproduce well on websites, smartphones and tablet computers.

UC spokesman Steve Montiel says officials are paying attention to the feedback, but there are no plans to drop the logo.

The university still plans to use its traditional seal on diplomas, acceptance letters and other official documents.
