I have a color image with red and blue color.
How can I find out the percentage of individual red and blue color.

Aditya, this is the third time you have asked this same question. Why do you keep asking when it has already been answered? Use comments to discuss. You can edit your old questions to update them.

Aditya, If your image is binary blue / red, this is easy. Otherwise, you need to define what is "red" (is it [1 0 0]?) and what is blue ([0 0 1]?). What if it's [0.95 0.05 0.05]? Is that red?
You might consider kmeans clustering. Check out clusterImg on the File Exchange; it can help you create separate color masks of your image. Then you can easliy count the number of pixels in the resulting binary masks.
Cheers,
Brett
