RGB vs CMYK Explained, What REALLY Matters When Printing Books

This is a question I get asked a lot, and it causes far more confusion than it needs to. In this video, I explain the real difference between RGB and CMYK, why RGB is used for screens and CMYK is used for print, and whether you actually need to worry about it when publishing books through Amazon KDP. I show a direct comparison using two printed copies of the same cookbook, one exported in RGB and the other in CMYK, both printed by Amazon. You’ll see just how small the difference really is on standard Amazon paper and why most self-publishers don’t need to panic or upgrade software purely for CMYK exports. I also explain when CMYK does matter, such as private printers, glossy paper, or full-page photo books, and when RGB is perfectly fine for KDP, even though everything ends up printed in CMYK anyway. If you’ve been stressing about colour modes, file sizes, Canva exports, or whether you’re doing something wrong, this video should put your mind at ease. #rgb #cmyk #amazonkdp
