    Ever needed a placeholder color for your lazy loaded table view cell image view? Typically can create a 1x1 pixel image in PhotoShop, add it to your project, then load it with UIImageNamed. Can't imagine how lots of effort and steps, and if the placeholder color are requested to be updated, you'd have to repeat the process all over again.

    If you needed work with this kind of situations a lot, lets do it programmatically and DRY! Consider the following UIImage+JTColor category.
