Creates a customizable color palette for categorical values or column names. Colors can be assigned automatically using a base palette or explicitly defined for specific values or names.\n
Assignment behavior:
\n \n
Categorical values: All unique values across the selected columns are combined, sorted in natural order, and assigned colors accordingly.
Column names: Colors are assigned based on their order in the input table.
\n Note: Explicit assignments take precedence. Unmatched values or names are assigned colors from the base palette.\n \n ","shortDescription":"Creates a color palette for categorical values or column names.","keywords":[],"deprecated":false,"streamable":false,"tags":["Views","Property"],"icon":"data:image/png;base64,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","sinceVersion":"5.10.0","views":[],"inPorts":[],"outPorts":[{"objectClass":"org.knime.core.node.port.viewproperty.ColorHandlerPortObject","color":"1eb9dc","dataType":"Color","optional":false,"name":"Color Palette","description":"A color palette object containing all color mappings."}],"dynInPorts":[{"groupName":"Table","groupDescription":"Input table containing category columns to which colors will be applied.
