Thank you for your response, great info.

And some more questions:

1) How can I determine if my image is in the sRGB format?  I am using images from a scanner, the metadata from the image only says that it is an RGB image.

2) So when the 'Average Color' function is using CIELab averaging, is it converting RGB values into the CIELab color space?

3) Is there a better way to get a mean color value for R, G, and B per a ROI (see photo example below)?  Can I batch process this?  I've tried using the multi-measure tool (after splitting the image into R, G, B slices) in the ROI manager, but the data output puts the values in an order that is not very useful.  To be more specific, the time it would take me to reformat the multi-measure output in excel would be too great.  I need the output to be in order by R, G, B per ROI per image so that I can convert the values to H, S, B.

Any help would be greatly appreciated, thank you!
