While working on an InDesign script that checks the links used in a file I decided to check what color profile has been used on images so I can output it to a log for the user however when I write my conditional to check if a link is a GIF I was unsure if a GIF could actually have a CMYK profile. When I research wikipedia:
The format supports up to 8 bits per pixel for each image, allowing a single image to reference its own palette of up to 256 different colors chosen from the 24-bit RGB color space. It also supports animations and allows a separate palette of up to 256 colors for each frame. These palette limitations make the GIF format less suitable for reproducing color photographs and other images with continuous color, but it is well-suited for simpler images such as graphics or logos with solid areas of color.
It mentions RGB only but it doesn't mention if a CMYK profile can be supported. So, can a GIF support a CMYK profile?
