Color Modifier
Summary
The Color Modifier modifies the color of each instance based on falloff values. It uses a color ramp (gradient) to map falloff attribute values to colors, enabling visually dynamic effects based on spatial relationships, proximity, or any custom falloff attribute.
You can customize the color palette using the Ramp parameter, which accepts either an internal ramp editor or an external Ramp TOP reference. This allows for flexible color mapping from smooth gradients to complex multi-color patterns.
Parameters

Group
Group
–
If there are input groups, specifying a group name in this field will cause this POPX to act only upon the group specified.
Falloff Attribute
Falloffattr
–
Specifies which attribute to use for falloff values that drive the color ramp lookup.
Open Ramp
