Identifying out-of-gamut colors
Most scanned photographs contain RGB colors within the CMYK gamut, and changing the image to CMYK mode (which you’ll do later in order to print the file) converts all the colors with relatively little substitution. Images that are created or altered digitally, however, often contain RGB colors that are outside the CMYK gamut—for example, neon-colored logos and lights.
Note
Out-of-gamut colors are identified by an exclamation point next to the color swatch in the Color palette, the color picker, and the Info palette.
Before you convert an image from RGB to CMYK, you can preview the CMYK color values while still in RGB mode.
