Hi, I'm a new user in ImageMagick. I would like to change the red color which appears to our sight into black color, but leave other color still the same. For example, I would like to change Santa Claus' red clothes into black, but the colors of other things which are not appearing red are still the same. The Christmas tree in that picture is still green.
Please help me!
Thanks in advance for any help.[/img]
