The System.Drawing.Color enumeration in .NET provides a whole host of colors and is very easy to use. For instance, if I wanted to change the background color of a form, I could use the following:
| MyForm.BackGroundColor = Color.White |
| MyForm.BackgroundColor = Color.FromArgb(CType(192, Byte), CType(192, Byte), CType(255, Byte)) |
