+   Selects which color values are used to calculate analytics.
 
+   :Combined: Calculate values based on the red, green, and blue channels.
+   :Red: Calculate values based on the red channel.
+   :Green: Calculate values based on the green channel.
+   :Blue: Calculate values based on the blue channel.
+   :Luminance: Calculate values based on the :term:`Luminance` of the image.

 Mean
-   The mean is the average value of all image pixels in specified channel
-   (combined, red, green, blue, luminance). It represents the overall brightness of the image
-   and can be used as such for setups that depend on how "bright" or "dark" the input is.

 Standard Deviation
    How much pixel values differ from the mean.
    A low standard deviation indicates that the pixel values tend to be very close to the mean.
    A high standard deviation indicates that the values are spread out over a large range of values.
