Dear Herbie,

Thank you for the helpful comments and suggestions.  I understand what you are saying about arbitrary leaf overlap but for my purposes it is still meaningful information.  I need a good estimate of percent coloration of the overall plant.

I only sent a pink and red example, and not a white example.  I assume the process would be the same?  

I am going to show my ignorance of the program as I don't know how to transform the picture to become CMYK.  

Step 2 - you say to "threshold the color channels according to the automatic "RenyEntropy"-scheme"  How do I do this?
 
Finally you say to that "After thresholding you can measure the selected area"  Again, I am just learning and don't know how to do this.

I'm afraid I need step by step directions on how to do these things.  They sound simple enough.  Unfortunately I am totally new and don't know how to do any of it.  If you could possibly give some more step by step directions, I would really appreciate it!

Emily
