The color conundrum
No device in the digital photographic workflow can reproduce the full range of colors viewable to the human eye. Each
device operates within a specific color space, which simply describes a range, or gamut, of colors that the device can
record, store, edit, or output. Some color spaces are bigger than others. For example, the CIE Lab space is large; the
sRGB space, used by many web browsers, is relatively small.
In addition, each device describes color either additively, using the RGB color model, or subtractively, using the CMYK
color model. Cameras and monitors use RGB; printers use CMYK.

Because of these varying color spaces, colors often look different depending on where you view them. Color
management systems use profiles to reconcile color differences among devices so that you can confidently predict the
color that you'll see when you share or print photos.
