I recently stopped developing ColorCatcher; the latest version is 5.0
The successor to ColorCatcher is ChromaKeep. In my opinion, the name ColorCatcher didn't quite capture the full scope of the program.
I believe the new name, ChromaKeep, does a much better job of that.

In 8 seconds, you will be redirected to the new ChromaKeep website.

If not, click ChromaKeep 1.0.
