VBA And Conditional Formatting or Other

[ajocius]

I'm running Windows XP with Excel 2010. I would like to be able to have a group of 19 boxes of which each box has a unique entry, ie 1, 3B, 5C etc. Each box I'd like to have a way in which when selected only the single or dual unique characters show as a color. See attached spreadsheet with sample. When a cell with lets say 1 is selected, a drop box appears and the color and description are shown. Select a color but only show the 1 and the color selected, leaving behind the description. How can I do this for all 19 boxes. This seems like its a classic conditional format. Unfortunately it appears to be several orders of difficulty than a normal conditional format. Any help would be great. Thanks.
