Good answers already, but I agree with a couple of points. Get yourself calibration gear, I use Eye One Match. You can name the calibration you do anything you want, I calibrate very month or so, so I name mine the date I do it. After that, if you are working with RGB files (I hope you use Photoshop) set your colour space for Adobe 1998. This is if you want to go full into photo editing. If you don’t then check out the System Preferences for you monitor in your Start Up menu to calibrate your screen manually. Follow the on screen instructions and that’s that!

Most professionals (to obtain consistent color) purchase a Hardware (plus software) package that will calibrate your monitor. There’s the Monaco Optix Pro, the Spyder, and other brand names, for monitor calibration. (The Monaco system is well-rated, but it’s expensive — over 300 dollars.)

With these hardware devices, you place a “puck” onto the monitor which actually measures what’s happening on your screen at the phosphor level (you also have to have a monitor which enables adjustments — a brightness control knob/screw, for example). These monitor calibrating devices will bring your monitor into compliance with a predefined standard for your monitor model.

There are cheaper ways — you can just eye-ball colors. If you have Adobe Photoshop you could create a custom RGB profile as a working space (you’d specify the gamma, whitepoint, and phosphor settings.)
