Image1 = im2double(imread('image\8.jpg'));
g=rgb2gray(Image1);
[row column page] = size(Image1)
mask = Image1(:,:,2) > Image1(:,:,1) & Image1(:,:,2) > Image1(:,:,3);
Image2 = Image1 .* mask(:,:,[1 1 1]);
figure,imshow(Image2);
title('light green');
mask = Image2(:,:,2) + 20 > Image2(:,:,1) & Image2(:,:,2) + 20 > Image2(:,:,3);
Image3 = Image2 .* mask(:,:,[1 1 1]);
figure,imshow(Image3);
title('dark green');

See my color segmentation demos in my File Exchange http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862
Or else search on the tag "leaf".
Or else use imseggeodesic(). Look up examples in the help for it.

i tried your demo. For some reason it's not working for my own images. it does not ask me the option to choose the color but works for the demo

Set a breakpoint on the call to menu(). Chances are you clicked somewhere and that popup dialog box then went underneath whatever you clicked on.

Remember when you im2double() you change the data to the range 0 to 1. Your value +20 suggests you are still thinking in terms of uint8 values in the range 0 to 255. If so then the corresponding increment in 0 to 1 range would be 20/255 rather than 20.
