Regarding ColorSync issues reported in a review:

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 "Display as sRGB" (selected by default) to convert the RGB values into the 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).

For more information about color meters and color space conversion, select Help from the menu bar and then "Learn about Color Conversion" or visit


Release Notes:

• Fixes an issue where "Show as ROMM RGB" would select "Convert to main display" and vice-versa

Thank you! - I can't understand why Apple either removed this feature, or failed to implement it back into new Lion apps. And while I think it's stilly to me to even have to look for an alternative solution, I'm glad you implemented one. It works exactly as I need it to. Thanks.

Useless - Does’t take color profile information into account so it gives the wrong values. “You had one job."

Version 1.8.1
Review by Adrian Perez Rivera

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.
