I was thinking about this recently.

Years ago, on a photo developing course, we were asked to print an image from a single colour negative onto several brands of colour photo paper.

All came out differently, and the reason was "gamut".

Different papers react differently across the spectrum they are being asked to recreate. One might have brighter reds, another duller greens, and some don't react to some colours at all (especially fluorescent tones).

The same thing happens between a digital photo and monitors and printers. So if you are trying to print something with, for example, a specific blue used in a company logo, you might hit snags. Even your camera sensor has its own gamut, so you can get tied in knots unless you have expertise in colour balancing and/or the pantone system.
