Blend modes control how a shape composites with the content below it in the layer stack. They are set in the Properties Panel under "Compositing."

Normal Group (Default)

Mode	Description
Normal	Standard alpha compositing. The element overlays content below according to its opacity.
Dissolve	At less than 100% opacity, pixels alternate randomly between fully opaque and fully transparent, creating a dithered transparency effect.

Darken Group

Mode	Description
Darken	Keeps only the darker pixels between the element and what is beneath it.
Multiply	Multiplies color values. Always produces a darker result. White is neutral (no effect); black produces black.
Color Burn	Increases contrast and darkens the base by reflecting the blend color. Stronger effect than Multiply.
Linear Burn	Darkens by decreasing brightness. Darker than Multiply in most cases.
Darker Color	Compares the full pixel values and keeps whichever is darker.

Mode	Description
Lighten	Keeps only the lighter pixels between the element and what is beneath it.
Screen	Inverts, multiplies, then re-inverts. Always produces a lighter result. Black is neutral; white produces white.
Color Dodge	Brightens the base by reflecting the blend color. Strong highlight effect.
Linear Dodge (Add)	Adds color values together. Strongly brightening; can quickly saturate to white.
Lighter Color	Compares full pixel values and keeps whichever is lighter.

Mode	Description
Overlay	Multiplies dark areas and Screens light areas. Increases contrast. 50% gray is neutral.
Soft Light	Similar to Overlay but gentler and less contrasty.
Hard Light	Similar to Overlay but the blend color controls the effect rather than the base.
Vivid Light	Burns or dodges by adjusting contrast depending on tone. Very high contrast.
Linear Light	Burns or dodges by adjusting brightness. Even more extreme than Vivid Light.
Pin Light	Replaces colors depending on the blend color's tone. Produces posterized-looking results.
Hard Mix	Reduces all colors to pure primaries (red, green, blue, cyan, magenta, yellow, white, or black).

Mode	Description
Difference	Subtracts one color from the other. White inverts the base; black has no effect.
Exclusion	Similar to Difference but lower contrast. 50% gray produces no change.
Subtract	Subtracts blend color from base. Can produce strongly darkened results.
Divide	Divides base color by blend color. Produces very bright, often over-exposed results.

Mode	Description
Hue	Applies the hue of the blend to the luminosity and saturation of the base.
Saturation	Applies the saturation of the blend to the hue and luminosity of the base.
Color	Applies both hue and saturation of the blend to the base. Useful for colorization effects.
Luminosity	Applies the luminosity of the blend to the hue and saturation of the base. Inverse of Color.
