If you like the general ideas discussed so far, but didn’t have complete success isolating areas based on hues, try choosing Image > Adjustments > Replace Color (Figure 8.36). In essence, Replace Color combines the Color Range command with the color-shifting capability found in the Hue/Saturation controls. The advantage of using Replace Color is that instead of having to figure out the exact Hue, Saturation, and Lightness settings necessary to get the desired result, you just define the desired color by clicking the color swatch at lower right in the dialog.
