RGB - CMYK in the information window

When I open Information window, can I choose to display RGB and CMYK information about each pixel (or other info if I want it, such as the Web color or Lab colors). I understand the RGB numbers are based on 255 (number of gray levels) and number of grayscale is in percent, but what is "scale" numbers CMYK, that they are based on or show me?

An example is that the color with RGB R255-B255 values CMKY C11 - Y79 values. What to do the 11 and the average of 79?

Best, David.

In the CMYK mode, each pixel is assigned a value in percentage for each of the process inks. The colors (highlighted) more light are assigned small percentages of ink colors quadri; the darker (shadow) colors higher percentages. For example, a bright red can contain 2% cyan, 93% magenta, 90% yellow, and 0% black. In CMYK images, pure white is generated when all four components have values of 0%.
