Introduction
The .NET Framework provides us with over 100 colours to use within the
System.Drawing namespace. In order that we know exactly what all these colours
look like here is a simple web based tool that uses Reflection to loop through
all the colours with the System.Drawing.Color struct and print them to the page.
