Understanding color space and color management can be one of the most difficult concepts to wrap your head around. What is the difference between Adobe RGB and sRGB? Why do magazines always print my images with funky colors? Why do I need different profiles for different devices?
Luckily photoshop guru Kevin Kubota has made a really useful video explaining how color management works. If you are simply displaying your images for the web then most of this won’t really matter but if your images are being printed, used commercially, or sent to different devices then you might run into problems.
