'Declaration Public NotInheritable Class Outlook2007ColorScheme
public sealed class Outlook2007ColorScheme
The UltraCalendarLook.Outlook2007ColorSchemes collection contains fifteen instances of the Outlook2007ColorScheme class, one for each of the color schemes seen in the 'Calendar Options' dialog of Microsoft® Outlook® 2007.
"Standalone" instances of the Outlook2007ColorScheme class can be created and assigned to an Owner's Owner.Outlook2007ColorScheme property. The constructor, which is publicly exposed, takes a single parameter of type System.Drawing.Color; this parameter determines the value of the BaseColor property, which is the color from which all other color properties exposed by this class are derived.
The color properties exposed by the Outlook2007ColorScheme class are formulated by increasing or decreasing the brightness (or luminosity) of the BaseColor. For this reason, colors whose luminosity component is relatively small or relatively large should be avoided when selecting the base color for a color scheme, since many of the colors subsequently returned by the properties of this class will be either too dark or too close to white to be aesthetically pleasing to the end user.
