is the area under a curve or between two curves?
otherwise, do you have a mask, in which every point which shall be green =1 and ever other =0?
then apply:
rgb=size(mask);
rgb(:,:,1)=0;
rgb(:,:,2)=mask;
rgb(:,:,3)=0;
imhsow(rgb);
if you do not have a mask, you have to create one... hope i could help you

For example, you could get the mask by thresholding:
mask = grayImage < someThresholdValue;
rgb(:,:,2) = 255 * uint8(mask);

look at this example, i think its the easiest way to get a mask
consider if the output values are correct. extraction of concrete pattern can be quite difficult and is an issue in many segmentation research studies...
