Specifies the color of objects displaying in dynamics in the model. Objects in dynamics have not yet been written to the model. For example, an object that you are moving from one location to another displays in dynamics until you finish the move. Click the arrow to select a different color. The color displays on the Preview so that you can verify that it does not conflict with your other selections. To return to the default color, click Default on the color picker. If you need additional colors, click More Colors on the color picker. This option is on the 3D Model Tab (Options Dialog).
