Multiplies the complements of the channel values, and then takes the complement of the result. The result
Screen
color is never darker than either input color. Using the Screen mode is similar to superimposing two different film
negatives and printing the result.
The result color is a lightening of the source color to reflect the underlying color by increasing the
Linear Dodge
brightness. If the source color is pure black, the result color is the underlying color.
The result color is a lightening of the source color to reflect the underlying layer color by decreasing
Color Dodge
the contrast. If the source color is pure black, the result color is the underlying color.
The Color Dodge mode from After Effects 5.0 and earlier, renamed Classic Color Dodge. Use
Classic Color Dodge
it to preserve compatibility with older projects; otherwise, use Color Dodge.
Multiplies or screens the input color channel values, depending on the underlying color. The result
Overlay
preserves highlights and shadows in the underlying layer.
Darkens or lightens the color channel values of the underlying layer, depending on the source color. The
Soft Light
result is similar to shining a diffused spotlight on the underlying layer. For each color channel value, if the source
color is lighter than 50% gray, the result color is lighter than the underlying color, as if dodged. If the source color is
darker than 50% gray, the result color is darker than the underlying color, as if burned. A layer with pure black or
white becomes markedly darker or lighter, but does not become pure black or white.
Multiplies or screens the input color channel value, depending on the original source color. The result is
Hard Light
similar to shining a harsh spotlight on the layer. For each color channel value, if the underlying color is lighter than
50% gray, the layer lightens as if it were screened. If the underlying color is darker than 50% gray, the layer darkens
as if it were multiplied. This mode is useful for creating the appearance of shadows on a layer.
Burns or dodges the colors by decreasing or increasing the brightness, depending on the underlying
Linear Light
color. If the underlying color is lighter than 50% gray, the layer is lightened because the brightness is increased. If the
underlying color is darker than 50% gray, the layer is darkened because the brightness is decreased.
Burns or dodges the colors by increasing or decreasing the contrast, depending on the underlying color.
Vivid Light
If the underlying color is lighter than 50% gray, the layer is lightened because the contrast is decreased. If the under-
lying color is darker than 50% gray, the layer is darkened because the contrast is increased.
Replaces the colors, depending on the underlying color. If the underlying color is lighter than 50% gray,
Pin Light
pixels darker than the underlying color are replaced, and pixels lighter than the underlying color do not change. If
the underlying color is darker than 50% gray, pixels lighter than the underlying color are replaced, and pixels darker
than the underlying color do not change.
Enhances the contrast of the underlying layer that is visible beneath a mask on the source layer. The mask
Hard Mix
size determines the contrasted area; the inverted source layer determines the center of the contrasted area.
For each color channel, subtracts the darker of the input values from the lighter. Painting with white
Difference
inverts the backdrop color; painting with black produces no change.
The Difference mode from After Effects 5.0 and earlier, renamed Classic Difference. Use it to
Classic Difference
preserve compatibility with older projects; otherwise, use Difference.
Creates a result similar to but lower in contrast than the Difference mode. If the source color is white, the
Exclusion
result color is the complement of the underlying color. If the source color is black, the result color is the underlying
color.
Result color has luminance and saturation of the underlying color, and the hue of the source color.
Hue
Result color has luminance and hue of the underlying color, and the saturation of the source color.
