title: Adding a legend for colors in ListView WinForms C#
body: <p>I have simple <code>ListView</code> with few columns and it's populated with data with background colors. There's like 5 colors in use so I would like to nicely show them next to <code>ListView</code> for easy reminder especially for people who list things once a month. </p>
  
  <p>Are there some kind of guidelines how to proceed with this before I start to do it on my own (<code>GroupBox</code> with Colored <code>Labels</code> describing meaning comes to my mind next to <code>ListView</code>)? </p>
