Select a color or edit a gradient
In
many contexts, you can click an eyedropper button to activate
the eyedropper tool, or you can click a color swatch to open a color
picker. If you use the Adobe Color Picker, you can also activate
the eyedropper from the Adobe Color Picker dialog box.
If
you click a gradient swatch for a stroke or fill in a shape layer,
or click Edit Gradient in the Timeline panel, the Adobe Color Picker
opens as the Gradient Editor, with additional controls for editing
gradients included at the top of the dialog box.

Choose a color picker Choose Edit > Preferences > General
(Windows) or After Effects > Preferences > General (Mac OS),
and do one of the following:To use the color picker provided by the
operating system, select Use System Color Picker.
To use the Adobe Color Picker, deselect Use System
Color Picker.
 Jeff Almasol provides the PickerSwitcher
script on his redefinery website, which toggles
the Use System Color Picker setting. Use this script when you prefer
to use the Adobe Color Picker for certain tasks, but the operating
system color picker for others, and want a quick way to change this
setting. This script works especially well in conjunction with the
LaunchPad panel, with which running the PickerSwitcher script is
as easy as clicking a button. To download the LaunchPad script,
go to the After Effects Exchange on the Adobe
website.
Select a color with the eyedropper tool- Click the eyedropper button, and move the pointer
to the pixel that you want to sample. The color swatch next to the
eyedropper button dynamically changes to the color under the eyedropper.
- Do one of the following:
To select the color of a single pixel,
click the pixel.
To sample the color average of a 5-pixel-by-5-pixel
area, Ctrl-click (Windows) or Command-click (Mac OS) the area.
Note: When sampling from within the composition frame
of the Composition panel, the eyedropper by default ignores the
composition background color and samples only straight color channels.
To sample color channels premultiplied with the composition background
color, press Shift as you click with the eyedropper. Shift-clicking
with the eyedropper samples colors as they appear in the composition
frame in the Composition panel.
You can use the Sampler
Sizer Radio script from the Leapfrog Productions website to change
the area sampled by the eyedropper tool.
 Press the Escape key to deactivate the
eyedropper.
Select a color with the Adobe Color Picker- Click a color swatch to display the Adobe
Color Picker.
- (Optional) To prevent panels from updating with the results
of your color selection until you accept the color by clicking OK,
deselect Preview in the Color Picker dialog box. The Preview option
is not available in all contexts.
Note: Selecting Preview is convenient for seeing the results
of your color selections before you commit them, but it can also
decrease performance, as new images are rendered for the preview
in the Composition panel or Layer panel.
- Select the component you want to use to display the color
spectrum:
- H
- Displays all hues in the color slider. Selecting a hue
in the color slider displays the saturation and brightness range
of the selected hue in the color spectrum, with the saturation increasing
from left to right and brightness increasing from bottom to top.
- S
- Displays all hues in the color spectrum with their maximum
brightness at the top of the color spectrum, decreasing to their
minimum at the bottom. The color slider displays the color that’s
selected in the color spectrum with its maximum saturation at the
top of the slider and its minimum saturation at the bottom.
- B (in the HSB section)
- Displays all hues in the color spectrum with their maximum
saturation at the top of the color spectrum, decreasing to their minimum
saturation at the bottom. The color slider displays the color that’s selected
in the color spectrum with its maximum brightness at the top of
the slider and its minimum brightness at the bottom.
- R
- Displays the red color component in the color slider
with its maximum brightness at the top of the slider and its minimum
brightness at the bottom. When the color slider is set to minimum
brightness, the color spectrum displays colors created by the green
and blue color components. Using the color slider to increase the
red brightness mixes more red into the colors displayed in the color spectrum.
- G
- Displays the green color component in the color slider
with its maximum brightness at the top of the slider and its minimum
brightness at the bottom. When the color slider is set to minimum
brightness, the color spectrum displays colors created by the red
and blue color components. Using the color slider to increase the
green brightness mixes more green into the colors displayed in the color
spectrum.
- B (in the RGB section)
- Displays the blue color component in the color slider with
its maximum brightness at the top of the slider and its minimum
brightness at the bottom. When the color slider is set to minimum
brightness, the color spectrum displays colors created by the green
and red color components. Using the color slider to increase the
blue brightness mixes more blue into the colors displayed in the
color spectrum.
- Do any of the following:
Drag the triangles along the color slider,
or click inside the color slider to adjust the colors displayed
in the color spectrum.
Click or drag inside the large square color spectrum
to select a color. A circular marker indicates the location of the
color in the color spectrum.
Note: As you adjust the color using
the color slider and color spectrum, the numeric values change to
indicate the new color. The top rectangle to the right of the color slider
displays the new color; the bottom rectangle displays the original
color. Click the bottom rectangle to reset the color to the original
color.
For HSB, specify hue (H) as an angle, from 0° to
360°, that corresponds to a location on the color wheel. Specify
saturation (S) and brightness (B) as percentages (0–100).
For RGB, specify component values. You can set colors
to under-range and over-range values (outside the range 0.0–1.0)
in an HDR project.
For #, enter a color value in hexadecimal form.
This color format is common in web workflows.
Edit a gradientA gradient is defined by color stops and opacity
stops. Each stop has a location along the gradient and a
value for color or opacity. The values between stops are interpolated.
By default, the interpolation is linear, but you can drag the opacity midpoint
or color midpoint between two stops to alter the interpolation.
Using Adobe Kuler swatches in After EffectsAdobe provides the Swatch You Want script in
a package of scripts for After Effects CS4 on the After Effects
Exchange on the Adobe website. The Swatch You Want
script imports and converts Adobe Swatch Exchange (.ase) files for
use in After Effects.
Jerzy Drozda, Jr. provides a video tutorial
and example project on his Maltaannon website that show how to
copy and paste from the Adobe Kuler desktop application to bring
color swatches into After Effects.
Mathias Möhl provides a
script on the After Effects Scripts website with
which you can load and use Kuler color themes.
