Sidebar ‣ Node
A unique node identifier inside this node tree.
Nodes can be given a title by modifying the text field.
By default, the node’s background color is defined by the user theme. This color can be overridden by selecting a custom color in this panel. Custom node colors can be used to provide a visual cue to help distinguish some nodes from others. The button to the right of the checkbox lets you save colors as presets for reusing later on (much like a palette).
The properties that are shown depend on the type of node selected, e.g. a Mix node has different properties than a Mask node.
