Different colour spaces are better for different applications, some equipment has limiting factors that dictate the size and type of colour space that can be used. Some colour spaces are perceptually linear, i.e. a 10 unit change in stimulus will produce the same change in perception wherever it is applied. Many colour spaces, particularly in computer graphics are not linear in this way. Some colour spaces are intuitive to use, i.e. it is easy for the user to navigate within them and creating desired colours is relatively easy. Finally, some colour spaces are device dependent while others are not - i.e device independent.
