Attached Link: Mastering Digital Color

Here is an article from Popular Photography that might help. I had a similar problem and found changing my Photoshop Color Settings.. for RGB to Monitor RGB, solved the problem. I think there was another setting somewhere that let me select web RGB, but I can't find that control panel right now. Hope that help and BTW, my output is still color correct for print. And your second image looks good. :)
