Graphics professionals aren't the only people who worry about the color accuracy of their monitors. These pros make their living working with images in one form or another. Making sure the colors they see on their monitors are the same colors seen in a project's final form can be the difference between keeping clients and losing them.

Nowadays, just about everyone works with images. They may keep a library of photos on their Macs, print images using color printers , and use digital cameras or smartphones with cameras that make capturing images as simple as point and click. When that bright red flower you saw in your camera's viewfinder looks muddy on your Mac's display and downright orange when it comes out of your inkjet printer, the problem is that the devices in the chain haven't been calibrated to ensure that a color remains the same throughout an entire process, no matter which device is displaying or producing the image.

Getting photos on your Mac to match the colors of the original images starts with calibrating the display. Professional calibration systems use hardware-based colorimeters, devices that attach to a display and measure the way it behaves in response to various images.

These systems are accurate but too expensive for most casual users. However, with a little help from your Mac's software-based calibration system, you can adjust your monitor so that the images you see on your display are a close match to the original versions. Most displays come with International Color Consortium profiles. The ICC files, usually referred to as color profiles, tell your Mac's graphics system how to display images accurately.

Your Mac comes preloaded with dozens of profiles for popular displays and other devices. However, color profiles are only a starting point. They may be accurate the first day you turn on your new monitor, but from that day forward, your monitor ages, and three important characteristics—the white point, luminance response curve, and gamma curve—all begin to change.

Calibrating your monitor can return it to like-new viewing conditions. All Macs come with Display Calibrator Assistant, a software-based calibration process. The Display Calibrator Assistant walks you through the calibration process. The Assistant displays various images and asks you to make adjustments until each image matches the description. For example, you may see two gray patterns and be instructed to adjust the brightness until the two images appear to be of equal brightness.

Before you begin calibrating your display, take the time to set up your monitor in a good working environment. Some obvious things to watch out for include preventing reflections and glare on the display. View the monitor straight on and don't look at the display from an off-angle while color calibrating it. There's no need to work in the dark. A well-lit room is fine.

The easiest way to launch the Display Calibrator Assistant is to use the Display preference pane. Click the Displays icon in the System Preferences window. Click the Color tab. Check the box in front of Show profiles for this display only unless you know you need to use a different profile.

If you want to use a different profile than the default that is selected, click it to highlight it. In OS X Yosemite Place a check mark in the Expert Mode box and click the Continue button. If you already have a color profile in use on your monitor, it is listed and highlighted under Display profile. If Apple doesn't make your current display, a generic profile has probably been assigned to it, but it is a good idea to check the monitor manufacturer's website to see whether it has an ICC profile you can download.

Calibrating the display is easier when you start from a specific profile rather than a generic one. If a generic profile is your only option, the Display Calibrator Assistant can still create a decent profile to use. It just may take a bit more fiddling with the calibrator controls. The Display Calibrator Assistant starts by helping you set the display's contrast and brightness. Access your monitor's built-in controls, which vary from manufacturer to manufacturer.

There may be an on-screen display system for brightness and contrast adjustments, or there may be dedicated control surfaces on the monitor for these adjustments. Check the monitor's manual for guidance, if needed. The Display Calibrator Assistant starts by asking you to turn your display's contrast adjustment to the highest setting. For LCDs , this may not be a good idea, because doing so increases the brightness of the backlight, consumes more power, and ages the backlight more quickly.

It's not necessary to crank contrast up to achieve an accurate calibration. You may also find your LCD has zero, or limited, contrast adjustments. Next, the Display Calibrator displays a gray image that consists of an oval in the center of a square. Adjust the display's brightness until the oval is just barely discernible from the square. Click Continue when done. The remainder of these steps apply to all monitors. The Display Calibrator Assistant determines the display's natural luminance response curve.

This is the first step in a five-step process; all five steps are similar. You are shown a square object made up of black and gray bars, with a solid gray Apple logo in the center. There are two controls. On the left is a slider that adjusts relative brightness; on the right is a joystick that allows you to adjust the tint of the Apple logo.

However, after clicking Detect Displays it was possible to get into expert mode as described above. Anyone really interested in colour profiles wont be using this bit of software to guess what it should look like. After struggling with ColorMunki for months I have abandoned it and just used the technique here to match to the print. Oh my god. This was driving me crazy as the profile definitely changed after upgrading to El Cap. Thanks so much.
