The Node Colors dialog window allows the selection of the colors to draw the internal and external nodes in the adjacency graph. A node is external if it has at least one adjacency with the outside, internal if it is not adjacent to the outside at all. The colors have to be selected from the list of valid colors given in Table 5.4. The standard colors are RED for the internal nodes and BLUE for the external nodes. The Node Colors selection dialog window is shown in Figure 5.47.
Click on OK to accept the modifications that you have made to colors used to display nodes in the adjacency graph. If you click on Cancel then all the modifications that you made will be discarded and the node colors will not be modified.
