The layer blending mode in After Effects is similar to the blending mode in Photoshop in terms of principle and application.
This article explains some of the blending modes that are unique to Ae. See the links for the same blending modes as PHOTOSHOP.
Pieces pieces pieces \
The normal group
Only when the opacity of the pixel is not 100% will it blend with the pixels of the layer below. \
See One of the Mixed modes: Normal Mode Group.
Normal,
Default mixed mode. \
Soluble Dissolve
Dynamic jitter Dissolve Dancing solvent
The random particles produced by the dissolution mode are static, while the dynamic jitter dissolution mode is random. \
Pieces pieces pieces \
Dark group
Compare the values of R, G and B channels of the pixels corresponding to the upper and lower layers, and take the darker value as the value of the blending effect, so as to achieve the effect of darkening the picture. \
See Blending Mode II: Darkening Mode Group.
Dimmed Darken
Multiplying the Multiply
Multiply mode is one of the most commonly used modes.
Color Burn
Enhance the dark and mid-tone areas by increasing the contrast.
Burn the Classic Color
Compared to the color burn mode, the image is darkened while greatly enhancing the contrast of the image.
It is reserved for compatibility with Ae 5.0 and earlier projects.
Burn linearly
Darker Color
That is, dark mode. Unlike other darkening modes, it compares the values (RGB) of the compound channels of the two layers and displays colors with smaller values, so no new colors are created.

Brighten group
Compare the values of R, G and B channels of the pixels corresponding to the upper and lower layers, and take the brighter value as the value of the blending effect, so as to achieve the effect of brightening the picture. \
See Blending Mode 3: Brightening Mode Group.
Add the Add
The RGB values of the corresponding pixels of the upper and lower layers are added separately to obtain a double brightness effect. \
Brighten Lighten
Screen Screen
That is, color filter mode. \
Color Dodge Color Dodge
Lighten the color by lowering the contrast.
Classic Color Dodge
Compared to color Dodge mode, the image lightens while retaining more dark details.
It is reserved for compatibility with Ae 5.0 and earlier projects.
Linear Dodge
Lighter Color
That is, the light-colored pattern.
Unlike the other brightening modes, it compares the value (RGB) of the compound channel between the two layers and displays the color with the higher value, so no new colors are created.
Pieces pieces pieces \
Overlay group
The bright ones become brighter and the dark ones darker, creating a stronger chiaroscuro effect.
See Mixed Mode Iv: Stacking Mode Groups.
Overlay Overlay
Superposition and strong light are the same algorithm, can be understood as “multiply + filter” combination. Overlay mode is the only mode in this group where the bottom layer dominates.
Soft Light Soft Light
Can be interpreted as a soft version of the bright light mode.
Strong Hard Light
Linear Light
Can be understood as the combination of “linear deepen + linear dodge”, the effect is strong.
The Light is Vivid Light
It can be interpreted as a combination of “color burn + color dodge”, so the color is more saturated.
Point Light Pin Light
It can be interpreted as a combination of “darken + lightened”.
Solid color Mix Hard Mix
That is, solid color blending mode. This mode results in the final result containing only six basic colors and black and white, with each channel having either zero or 255 pixels.

Difference between groups
Create a blending effect based on the color difference between the corresponding pixels of the upper and lower layers. \
See Mixed Mode 5: Difference Groups. \
Differential Difference
The absolute value of the corresponding pixel subtracted based on the primary color channel.
Classic Difference
It is reserved for compatibility with Ae 5.0 and earlier projects. The performance in the dark region is better than the difference pattern.
Eliminate Exclusion
Similar to difference mode, but with lower contrast.
Subtracting the Subtract
The value of each channel in the lower layer minus the value of the corresponding channel in the upper layer. If the result of subtraction is negative, the shear is 0.
Division by Divide
That is, partitioning patterns.
Pieces pieces pieces \
Color group
Blend the upper and lower layers based on the color three elements.
See Blending Mode 6: Color Mode Group. \
Hue Hue
Saturation Saturation
Color Color
Luminosity Luminosity
That is, lightness mode.

Mask set
This set of modes is used to convert the current layer into a mask for all the layers below, overcoming the limitation that the orbit mask can only work on one layer. \
Stencil Alpha
Use the Alpha channel of the top layer as a mask for all the layers below. \
Stencil Luma\
Use the brightness channel of the top layer as a mask for all the layers below.
Silhouette Alpha\
Invert the Alpha channel of the top layer as a mask for all the bottom layers.
Silhouette Luma
Invert the brightness channel of the top layer as a mask for all the layers below.
Pieces pieces pieces \
Trimming group
Alpha Add Alpha Add
Seams can occur between layers when the layers are aligned, or when the Alpha channels of the upper and lower layers are inverted. This pattern is used to remove visible edges for seamless composition. \
Luminescent Premul
When layer materials are using the pre-multiplied Alpha channel, after blending, prevent trimming those color values by adding them to the final effect that exceed the Alpha channel.
When applying this pattern, the best effect should be to interpret preloaded Alpha channel footage as a direct Alpha channel. \
