Lighten Each result color channel value is the higher (lighter) of the source color channel value and the corre-
sponding underlying color channel value.
Screen Multiplies the complements of the channel values, and then takes the complement of the result. The result
color is never darker than either input color. Using the Screen mode is similar to superimposing two different film
negatives and printing the result.
Color Dodge The result color is a lightening of the source color to reflect the underlying layer color by decreasing
the contrast. If the source color is pure black, the result color is the underlying color.
Classic Color Dodge The Color Dodge mode from After Effects 5.0 and earlier, renamed Classic Color Dodge. Use
it to preserve compatibility with older projects; otherwise, use Color Dodge.
Linear Dodge The result color is a lightening of the source color to reflect the underlying color by increasing the
brightness. If the source color is pure black, the result color is the underlying color.
Lighter Color Each result pixel is the color of lighter of the source color value and the corresponding underlying
color value. This is similar to Lighten, but Lighter Color does not operate on individual color channels.
Overlay Multiplies or screens the input color channel values, depending on the underlying color. The result
preserves highlights and shadows in the underlying layer.
Soft Light Darkens or lightens the color channel values of the underlying layer, depending on the source color. The
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.
Hard Light Multiplies or screens the input color channel value, depending on the original source color. The result is
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.
Linear Light Burns or dodges the colors by decreasing or increasing the brightness, depending on the underlying
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.
Vivid Light Burns or dodges the colors by increasing or decreasing the contrast, depending on the underlying color.
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.
Pin Light Replaces the colors, depending on the underlying color. If the underlying color is lighter than 50% gray,
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.
Hard Mix Enhances the contrast of the underlying layer that is visible beneath a mask on the source layer. The mask
size determines the contrasted area; the inverted source layer determines the center of the contrasted area.
Difference For each color channel, subtracts the darker of the input values from the lighter. Painting with white
inverts the backdrop color; painting with black produces no change.
Classic Difference The Difference mode from After Effects 5.0 and earlier, renamed Classic Difference. Use it to
preserve compatibility with older projects; otherwise, use Difference.
