**F.Y.I.---a great tool that I've been using to help me modify the colors in RainMeter skins to match my desktop colors (wall, etc.) is this cool lil creation by ActiveColors:
Even though Dovlet (ActiveColors) says that he's "not a coder", and he's told me that he should have added more features to his Picolor tool, I personally think it's pretty damned awesome as it is. Sure saves time, keeps me from having to open PS or Paint.net, or find color-codes online. Try it, you'll like it. Be sure to check out his other awesome creations, like his RainMeter skins. He has created many, his Path 1.1 being the latest (at the time of this posting); it was made to compliment the Path Windows 7 visual style---and is killer. All of his stuff is super-duper tight.
