As most of us know by now, how our eyes see things is not necessarily the same as our digital cameras. Our eyes adjust to things that our camera may not necessarily be able to translate into our actual photos. When it comes to colors the simplest analogy is to compare available colors within the different color spaces to the different size boxes of crayons available. The smallest box may offer only eight colors while the super huge box offers over a hundred colors to choose from. The different color spaces and our printers work the same way, each offering a different gamut or array of colors. Not all printers are capable of printing all the colors available so that becomes a limitation also.
