Am I the only person who has walked outside and discovered the black pants I put on were actually blue? To see a “true” color we need to view it under a “true” light source. To accurately match colors we need to view them under the same light source. Daylight is the accepted norm, to be more specific, a bulb with a color temperature of 5000k and CRI (color rendering index) of 90+. These bulbs are generally labeled as “Natural Light’. All cameras have a color bias and not all colors will photograph accurately. Although your camera’s Auto Color Balance isn’t exact, it will work fine for most pictures, but when you need exact color matches, you need to control the light – from the light you photograph with to the light with which you view the print.
