VMD maintains a database of the colors used for the molecules and the other graphical objects in the display window. The database consists of several color categories; each color category contains a list of names, and each name is assigned a color. The assignment of colors to names can be changed with this form. There are 16 colors, as well as black (the VMD color map), and this form can also be used to modify the definitions of these 17 colors. For more about colors, see the chapter on Coloring.
To see the names associated with a color category, click on the category in the Category browser located on the left side of the form. Click on the name to see the color to which it is mapped. To change the mapping, click on a new color in the browser to the right of the Category browser. For instance, to change the background to white, pick `Display' in the left browser and `Background' in the center one. The right browser will indicate the current color (which is initially black for the background). Scroll through the right browser and select white to change the background.
