Solved Start screen colour in windows 8

HERE IS THE PROBLEM.WHEN I CHANGE THE HOME START SCREEN COLOUR IT WILL AUTOMATICALLY CHANGE INTO PURPLE COLOUR WHY ?HELP ME....,

I'm sorry to hear that. Didn't find any solution to this.

I wanna add that I also see the purple background but only during boot and restarts.

Seems to be the default color, the one you get to see first from the clean (DVD start color) install.

Thanks for clarifying my doubt

Sorry for late reply... open your charms bar, then move your cursor to sync your settings... enable your microsoft account, then check whether metro personalization is turned on or not..... mine is enabled by default.... you could see my snap of it
