The color dialog’s function is to allow users to choose colors. For example, you might use this in a drawing program to allow the user to set the brush color.

The static functions provide modal color dialogs.

The static getColor() function shows the dialog, and allows the user to specify a color. This function can also be used to let users choose a

color with a level of transparency: pass the ShowAlphaChannel option as an additional argument.

The user can store customCount() different custom colors. The custom colors are shared by all color dialogs, and remembered during the

execution of the program. Use setCustomColor() to set the custom colors, and use customColor() to get them.
