This is an inbuilt function function provided by PPWIZARD.
This function takes a single parameter and sets the current color to one of the following color names:
Any color name that begins with "?" is automatically a valid color even if you have never defined it. It provides you with a range of colors that are not used by PPWIZARD so you can change color to any value(s) you wish to configure without effecting any existing PPWIZARD facilities.
See the color configuration section for more information about the color names and how the colours can be configured.
