What program are you using - Photoshop Elements or Premiere Elements, what version, and on what computer operating system is it running?
If you are using Photoshop Elements and not Premiere Elements, you have posted in the wrong forum. In that case, you want to post in the Adobe Photoshop Elements Forum. Somehow your thread got posted in the Adobe Premiere Elements Forum (video editing).
If your program is Premiere Elements, I will give you a how to for what you want to do using Premiere Elements for your video project.

Note to mod:
Please move to the Photoshop Elements forum.
It is premature to move this thread to Photoshop Elements Forum until we know the program and version involved.
There is a way in Premiere Elements to do selective coloration.
Note to mod: Although there is a strong likelihood that this is a Photoshop Elements question, please hold on transfer of thread from Adobe Premiere Elements Forum to Adobe Photoshop Elements Forum until originator of thread supplies information about program involved.
