Colour management products can be divided into two broad groups -
colorimeter based products (for measuring colour emmissive devices,
i.e. monitors) and full spectrophotometers (which can measure the
colour of both backlit and reflective objects, i.e. prints, monitors,
fabrics, and pretty much anything else!).

Colourimeters
Devices for calibrating monitors only
The first thing you should do before doing anything at all in digital imaging is to calibrate your monitor.
Calibrating
your monitor is the most important step in any digital imaging workflow
- how can you produce beautiful images if you can't see the images
accurately on your screen?
It's true all monitors vary,
but monitor calibration is not a subjective process - all digital
imaging revolves around viewing images on a properly calibrated
monitor. Calibrating your monitor with a hardware device is the only
really accurate way of working with digital images.
99% of
people working in digital imaging only need a colourimeter device.
Ranging from about $150 to $500, these devices will calibrate and
profile your monitor. They have an internal sensor that reads the
colour coming out of your screen.
Once you have calibrated
your monitor (a simple ten minute process), you will be looking at, and
therefore making decisions based upon, accurate colour. This is
absolutely the core aspect of a colour accurate workflow. The process
needs to be repeated regularly as monitors drift over time, thus owning
your own device is the only sensible long term solution (if you rent a
device or hire someone to do this for you, you will very soon have
spent more than buying your own in the first place!).
Combined with a high quality custom profile ICC service (if you're doing your own printing), you will be able to easily achieve accurate colour across your entire workflow.

Spectrophotometers
Devices for measuring and calibrating just about anything!
People
with a greater interest, or investment, in colour may find themselves
in need of a full spectrophotometer. These devices can be used to
calibrate and profile just about any colour device or system, including
monitors, printers (both RGB driven and CMYK driven), projectors,
scanners, and take spot colour measurements of just about anything from
fabrics to packaging to skin tones!
Generally you should
only consider one of these systems if you have a strong interest in
colour and have several devices you wish to calibrate and profile, or
use a great variety of media and want to make a significant number of
your own custom profiles. If this is not the case, a custom profile service
will often be a better value and quality option, as our custom profiles
are made with the very best of equipment and techniques that are
noticeably more sophisticated than the beginner systems.
Spectrophotometers
start at about $1000 (with really good systems adequate for most people
costing about $2500, and cream-of-the-crop systems costing $10000 or
more).
