The purpose of Colour management is to ensure predictable colour across image capture, retouching and distribution (screen, print, repro etc).
Colour management is a process that depends on a series of individual steps being done correctly across all devices and processes. Colour management only works as it should when each of these steps are done correctly.
An important keystone to colour management is a good quality screen calibration device, buying one and using it correctly will be a good start on the road to learning colour management.
Colour management is not fixed to any one standard, for instance the common photography monitor target of 6500K will not show a good colour preview for repro as the whitepoint is incorrect for the yellowish/redish paper stock used, this needs a setting of nearer 5000K.
Understanding the subtlety of colour management is a journey.
