No, the law library does not have color printers. If you need an on campus printing option, BYU has several Print Centers or Printer Kiosks across campus.
The Y App can help you find the closest pharos printer. The Print and Mail website provides more information about these options.
BYU Law provides Co-Op printers for BYU Law students. To learn more about the cost, how to install it and use it, see the BYU Law page on Co-Op printing.
