Color adjustment commands

You can choose from the following color adjustment commands:

Auto Color command Quickly corrects the color balance in an image. Although its name implies an automatic

adjustment, you can fine-tune how the Auto Color command behaves. See “Remove a color cast with Auto Color”

on page 185.

Levels command Adjusts color balance by setting the pixel distribution for individual color channels. See “Adjust

color using Levels” on page 162.

Curves command Provides up to 14 control points for highlight, midtone, and shadow adjustments for individual

channels. See “Curves overview” on page 163.

Photo Filter command Makes color adjustments by simulating the effects of using a Kodak Wratten or Fuji filter in

front of a camera lens. See “Change the color balance using the Photo Filter command” on page 182.

Color Balance command Changestheoverallmixtureofcolorsinanimage.See“ApplytheColorBalancecommand”

on page 182.

Hue/Saturation command Adjusts the hue, saturation, and lightness values of the entire image or of individual color

components. See “Adjust hue and saturation” on page 168.

Match Color command Matches the color from one photo to another photo, from one layer to another layer, and

from a selection in an image to another selection in the same image or a different image. This command also adjusts

the luminance and color range and neutralizes color casts in an image. See “Match the color in different images” on

page 176.

Replace Color command Replaces specified colors in an image with new color values. See “Replace the color of

objects in an image” on page 178.

Selective Color command Adjusts the amount of process colors in individual color components. See “Make selective

color adjustments” on page 181.

Channel Mixer command Modifies a color channel and makes color adjustments not easily done with other color

adjustment tools. See “Mix color channels” on page 179.

Make a color adjustment

All Photoshop color adjustment tools work essentially the same way; they map an existing range of pixel values to a

new range of values. The difference between the tools is the amount of control they provide. For an overview of the

color adjustment tools, see “Color adjustment commands” on page 158.

submenu. This method permanently alters the pixels in the active layer.

The second and more flexible method is to use an adjustment layer. Adjustment layers let you experiment with color

and tonal adjustments without permanently modifying the pixels in the image. The color and tonal changes reside

within the adjustment layer, which acts as a veil through which the underlying image layers appear.

1 If you want to make adjustments to a portion of your image, select that portion. If you make no selection, the

adjustment is applied to the entire image.
