Choose a CMYK equivalent for a non-printable color
Some colors in the RGB, HSB, and Lab color models cannot be printed because they are out-of-gamut and have no equivalents in the CMYK model. When you choose a non-printable color in either the Adobe Color Picker or the Color palette, a warning alert triangle appears. A swatch below the triangle displays the closest CMYK equivalent.
Note: In the Color palette, the
alert triangle is not available if you are using Web Color Sliders.
To choose the closest CMYK equivalent, click the
alert triangle 
in
the Color Picker dialog box or the Color palette.
Printable colors are determined by the current CMYK working space defined in the Color Settings dialog box.
