Multiply For each color channel, multiplies source color channel value with underlying color channel value and
divides by maximum value for 8-bpc, 16-bpc, or 32-bpc pixels, depending on the color depth of the project. The result
color is never brighter than the original. If either input color is black, the result color is black. If either input color is
white, the result color is the other input color. This blending mode simulates drawing with multiple marking pens on
paper or placing multiple gels in front of a light. When blending with a color other than black or white, each layer or
paint stroke with this blending mode results in a darker color.
Color Burn The result color is a darkening of the source color to reflect the underlying layer color by increasing the
contrast. Pure white in the original layer does not change the underlying color.
Classic Color Burn The Color Burn mode from After Effects 5.0 and earlier, renamed Classic Color Burn. Use it to
preserve compatibility with older projects; otherwise, use Color Burn.
Linear Burn The result color is a darkening of the source color to reflect the underlying color. Pure white produces no
change.
Darker Color Each result pixel is the color of darker of the source color value and the corresponding underlying color
value. Darker Color is similar to Darken, but Darker Color does not operate on individual color channels.
Add Each result color channel value is the sum of the corresponding color channel values of the source color and
underlying color. The result color is never darker than either input color.
Lighten Each result color channel value is the higher (lighter) of the source color channel value and the corresponding
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 projecting multiple photographic
slides simultaneously onto a single screen.
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. Lighter Color 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 whether or not the underlying color is
lighter than 50% gray. 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.
