I have to count presence of any colour if its number of pixels is more than 5% of total number of pixels.

With 16 millino colors possible in a24 bit RGB image, probably no color has that much. You'd be best off defining a limited number, like 5 or 10, color ranges. Then like Daniel said, use the Color Thresholder App to get the area fraction for each color range that you specify.

the easiest way would be using the Color Thresholder App to create function for the each color you want.
