Photoshop's Color Picker is chock full of more colors than a designer can imagine. That's the good news. The bad news is that a lot of the very bright super-saturation colors won't reproduce on a full-color press. How can you tell whether your color is out of the CMYK color gamut? This technique shows you.
TRY IT To check for out-of-gamut colors, use the Eyedropper tool and click a color you want to investigate. After the color appears in the Foreground color swatch, click that color swatch to launch the Color Picker.
As shown in the following illustration, the gamut-warning symbol looks like a triangle with an exclamation point. It only appears to the right of the color sample box if the selected color is out of gamut. If it does not appear, your color will most likely appear on press very close to how it appears onscreen. If the gamut warning does appear, notice that directly beneath the symbol is a small rectangle with a similar yet less-saturated color. This is a more accurate representation of how your color will appear when output on a CMYK press.
