Is there a special program to do this or is this built in to Photoshop? Does Photoshop tell you the values of absolute black or white or green etc; expressed numerically? And I need a matched monitor?

Built in. It's all part of a color-managed workflow, where each device is profiled/calibrated and photoshop knows the info. In other words, your computer should have a profile for your monitor (a generic one like sRGB, or a factory-supplied default, or a profile measured with a calibration instrument); your camera records things in a particular color space like sRGB or as a raw file that has known characteristics from the maker; your printer/paper combination can have a profile, (or Photoshop may output in a standard space while the manufacturer's printer driver converts the color to ink values). Photoshop converts everything into its own working space for manipulation and then renders it in the monitor space for viewing and the printer/paper space for printing.
