I'm using System.Drawing.Color, is there anything in Visual Studio that can display the color for the name?
For example if I used Color.Cornsilk
what would color would be displayed?
The Windows Forms properties window allows you to select Color related properties using a "Color Picker" that displays the actual color next to the name.
Just type in the color name within the property value area, press enter, and if the name is a known .NET color, it is shown.
