Whats the difference between device dependent and device independent?
A device dependent color space is a color space where the color produced depends on the equipment and the set-up used to produce it. For example the color produced using pixel values of [rgb = 250,134,67] will alter as you change the brightness and contrast on your display. In the same way if you change your monitor the red, green and blue phosphors will have slightly different SPD’s and the color produced will change. Thus RGB is a color space that is dependent on the system being used, it is device dependent. A device independent color space is one where the coordinates used to specify the color will produce the same color wherever they are applied. An example of a device independent color space (if it has been implemented properly) is the CIE L*a*b* color space (known as CIELab). This is based on the HVS (Hue/Value/Saturation) as described by the CIE system (see below to know what CIE stands for). Another way of looking a device dependancy is to imagine our RGB cube within our perce
