You set colors for many elements in Revit LT, such as objects, lines, annotation symbols, materials, rooms, and phasing. When you select colors, the standard Windows color dialog opens. If you click PANTONE from the Windows color picker, the PANTONE color dialog opens.
You can specify No Color in the Windows Color dialog to not associate a color with a particular item. This does not mean the item has no color. A component can assume its color from a parent category or use black. For example, if you specify No Color for Door Panel, but Doors are defined as brown, the Door Panel displays in brown.
