yogiyang	Posted - Dec 05 2018 : 05:04:51 Hello, I have a need to replace a color as selected by user by clicking on an image with a color as selected by use. In this image I want to replace the black color with blue color. I need to replace the color in such a way that all shared of black (and gray) should be replaced with blue as per their intensity (meaning if black is 100% then replace with blue at 100%). Again none of the other colors (shades) should be disturbed. How can we do this? TIA Yogi Yang
