How to change tiles' background color in Windows 8.1 start screen?

Have you checked in the Store? There are a number of freebies in there: http://apps.microsoft.com/windows/en-gb/app/custom-tiles-maker/6192f3b0-03e5-421c-82f4-33ae16537559

I can't believe there isn't a Group Policy setting or registry entry that could be used to decide whether Windows 8.1 will display tiles with a uniform background, or with an arbitrary colour picked from the icon.

Someone in Windows development was able to add this 'feature' to Windows 8.1 and nobody was able to prevent it reaching the finished product.

Thanks, I'd seen that already. It's interesting, though; I could imagine the author of that article having a slightly negative opinion of the 8.1 tile behaviour, the way it's described.

It says something when MS reworks the Office icons so they don't look so horrible under 8.1. Rather than fix the problem in 8.1!

Does this have to do with the color of the screen the tiles are on or the actual color of the tile itself? I read it through and it seems to do with the color round all the tiles (screen background color as opposed to the tile color itself).
