Anneliese,

An RGB image has three 8-bit channels, each with a 0-255 range of pixel
intensities. The color is what you call any of these channels: the first red,
the second green, the third blue. So honestly I don't understand your
question!

If the image had a single channel, then I can easily see how to go about it.

Or, do you want to use the three channels as if they where one channel only?
Then convert the image to 8-bit first, then retrieve the pixels and count the
ammount that fall within each range, and divide by the total -you can do that
with a macro as well.
