Blend + Composite Reference

Two overlapping soft circles illustrate how Chromatose combines two Generators (A = Magenta, B = Cyan) using every blend mode + composite operator combination.

Supported Composite Modes

• Over - Places the current layer over what’s beneath wherever its pixels have opacity.
• Atop - Shows the current layer only where lower layers already have content; outside that area the lower layers remain visible.
• Inside - Keeps only the portion of the current layer that overlaps the opaque area of lower layers.
• Outside - Keeps only the portion of the current layer that falls outside the opaque area of lower layers.
• XOR - Displays pixels where either the current layer or the layers below are opaque, but not where both overlap, creating a cut-out look.

Supported Blend Modes

• Normal - Replaces the underlying pixels with the current layer.
• Add - Adds color channels, brightening the result like stacked light.
• Subtract - Subtracts the top layer’s channels from the bottom layer, darkening or inverting areas.
• Multiply - Multiplies channels, darkening and mixing colors like overlapping gels.
• Difference - Shows the absolute difference between layers, yielding high-contrast results.
• Color Dodge - Divides the bottom layer by the inverted top layer. This lightens the bottom layer depending on the value of the top layer: the brighter the top layer, the more its color affects the bottom layer.

Intersection Colors

Generator A (bottom layer) = Magenta (R: 1, G: 0, B: 1),
Generator B (top layer) = Cyan (R: 0, G: 1, B: 1):
