I often hear people using the terms Color Space and Color Model interchangeably. However, if I understand correctly, they are two different things. Please advise as to the accuracy of the following statements which sum up my understanding of these concepts...
A Gamut, simply put, is a range of possible colors. It could be 10 million colors or just 10 colors. So if you had a box full of acrylic paint tubes and you decided to pick out 10 of them, then that would be your gamut. You'd have a 10 color gamut to work with.
A Color Model is like a mapping and/or naming convention for colors. It's basically a way of organizing and notating colors, or building a color design, like the Munsell system which is a color model, not a color space, right?
Sticking with the paint tube analogy, a Color Model is a like a blank "Paint By Numbers" canvas. You see the outlines of an image, with numbers or notations inside dictating which color belongs where. So you apply your gamut to this color model and voila, you have a color space which is something you can use to make informed and deliberate selections from which to chose colors.
Therefore: Color Model + Gamut = Color Space
So, when you add a specific gamut or range of colors to a mapping system, you have a very well organized set of colors to work with and chose from, which is called a color space. This is very useful for digital images...
Is this right, or am I completely off? I'd really appreciate it if anyone could shine some light on these concepts for me. Many thanks.
