Regarding ColorSync issues reported in a few reviews:

All color meter utilities in OS X see the RGB values sent to the display. These RGB values are in the display's color space. You should use "Show as sRGB" or "Show as Display P3" to convert all values into a standard color space.

No color meter utility can see the raw RGB values inside of an image file, as they will have undergone at least one color space conversion by the time they reach the display buffer. The only way to accurately sample the original raw values is to open the image in an editor and use that editor's native color picker or eyedropper tool (for example, the Adobe Color Picker in Photoshop).

Must-have for videographers, photographers, web designers, and anyone working with color

I work a lot with RGB video archival and have relied heavily on the built-in Digital Color Meter for accuracy verification. Classic Color Meter takes that concept and supercharges it, giving you a bunch of extra features that significantly enhance the tool’s effectiveness. You can convert between multiple monitor profiles, view 16-bit RGB, hold a color and convert it to another space, float the window above everything else, see when a color conversion is happening, and a lot more. It even uses less CPU than Digital Color Meter. If you’re wondering if it’s worth using over the free built-in utility, the answer is a solid yes.

Excellent utility

Every developer should have a copy so you know exactly what color that designer wants you to reproduce. A bargain at $3, should cost more like $30.

Indispensible utility app

I've used this app for years and highly recommend it as a replacement for the built-in DIgital Color Meter is OS X.
