How can I floodfill by differ of Color?

edited August 2013 in Need Help
I know there is a filter named Black Floodfill, it will execute painting(x, y) . But I want floodfill by differ of color. For example, if differ of Red(RGB) > 20, then floodfill this area.
Is that possible in CB? or there is another way to do the same job?

    Use Exchange Colour than. This is using The defined colour +-20.
  • "Exchange Colour" only have parameters: Old Color and New Color. where can i input "20"?

    Thats used by default....if the colour next to it is almost the same, it is treated as the one entered.
