With Photoshop's Gamut Waming active, you can add a Hue/

Saturation adjustment layer and reduce the saturation while watching its effect on the RGB image's colors. Here I have begun to drag the overall or Master saturation to the left and this has reduced the out-of-gamut areas. The Edit drop-down box also lets you adjust individual colors, which may be useful if you are working with a split-toned picture. Alternatively, use a Selective Color adjustment layer.
