To make changes to individual colors in the image, use the Hue/Saturation tool. With this tool you can make changes to individual ranges of colors in the image; e.g., you can change the cyan pixels to make them bluer, or you can change the red pixels to make them more saturated. This is a powerful tool to make subtle but effective changes to colors.

Digital colors are typically represented by values of Red, Green, and Blue. Colors can also be represented by values of Hue, Saturation and Lightness (HSL). The Hue provides a value for the shade of the color (red, orange, yellow, etc.) and the Saturation a value for the intensity of the color.

As the Color Balance dialog allows changes to R, G or B values, the Hue/Saturation dialog allows independent changes to Hue, Saturation, and Lightness values.
