To change the colors in an appearance scheme

Choose View > Appearance ().
Select the appearance scheme (if a plan or perspective is the active window, the selection is already the scheme set for that window).
Select the item from the drop-down list (if changing plotting colors skip this step).
Click on the color selection box for the item and choose a color.

Lines of drawn objects can be set to solid, dashed, or dotted. Reference lines have Line Type and Line Width properties that are independent of the appearance scheme setting.

The transparency of all Strip Plots in both 2-D and 3-D are controlled via the Transp. % control in the Appearance Settings dialog. This setting is used to modify the transparency already set in the default strip plot colors defined.
