The Color -> Colorize option is grayed out
We're working on a 8th grade project:
After installing the programs we're able to start GIMP, open the 3 FITS files for x-ray pictures. However, when we go to colorize the files, the Colorize option is grayed out - disable.
Our research has not been able to get this option enabled. colorize_issue.docx
Notice in the screenshot that the colorize option is disabled. Any help with this will be greatly appreciated.
