You can assign a specific color for cables when editing wires or in a Cable Wire Library. The color is reflected on the cable in the cable part.
To define a color when editing wires, in the Edit Wires PropertyManager, click More Properties. In the Edit Attribues dialog box, double click a color under the SWColor column and select a color from the Color dialog box.
To define colors in an existing Cable Wire Library, click and select Cable Wire Library Wizard.
