Hello,
I am doing a research project on how pumice rocks change color with varying amounts of heat. My findings thus far are that as rocks are exposed to higher temperatures, they oxidize and turn darker and darker shades of red.

I am attempting to quantify my data using Image J. I want to be able to upload my digital images of the rocks into the program, convert my images into RGB images and then determine the mean occurrence of red, green, and blue in each image (potentially with color histograms?). My ultimate goal is to quantitatively represent the color change occurring as the rocks change color with heat by determining the amount of red, green, and blue in each image.

Is this possible with this program? Any help would be much appreciated.
