Using Levels to adjust color (Photoshop)

In addition to setting the tonal range, you can use Levels to adjust the color balance of an image.

To use Levels to adjust color balance:

1. Place a color sampler on an area of neutral gray in the image.
2. Open the Levels dialog box. (See Making color adjustments.)
3. Do one of the following:
• Double-click the eyedropper tool in the Levels dialog box to display the Color Picker. Enter the values you want to assign to the neutral gray, and click OK. Then click the color sampler in the image.
• Click Options in the Levels dialog box. Click the Midtones color swatch to display the Color Picker. Enter the values you want to assign to the neutral gray, and click OK.

In general, assign equal color component values to a neutral gray. For example, assign equal red, green, and blue values to produce a neutral gray in an RGB image.
