Question
How do I check if my file is in CMYK or RGB?
Answer
Both Photoshop and Illustrator show the color mode right in the interface, so it only takes a second to confirm.
- Photoshop: look at the document title bar, where the mode appears in parentheses.
- Illustrator: check File then Document Color Mode.
- InDesign: the mode is set per document and applied at export.
For anything headed to print, keep the file in CMYK. Save RGB for screens and digital assets.
