title: Sorting Hex Colors using C#
body: <p>Im working on an MVC 3.0 application using C# code.
  I have a "Color" table related to "Products" table. 
  The value of each color which is hexadecimal (for example #FFFFFF) is saved in a nvarchar field "value". 
  In my products client section, I have a DropDownList for colors of a specific product. 
  So I need to sort these colors in the dropDownList from lighter to darker... 
  Any help will be appreciated... :) </p>
