My fellow evangelist Ed Donahue shows you the hex color codes:

In my own projects I really like to have correct colors. With Windows 8 coming out, more and more of my projects are around Windows 8. I’m not much of a designer, but sometimes I like to play pretend. I was able to grab these colors from Windows 8 RTM. I’m only including the HEX code because RGB would have been a pain to copy from the programs I use. If you need RGB, there are lots of HEX to RGB color converters online. I hope you find these useful!

This first set of colors is from the tiles found on the Start Screen, such as Mail, Calendar, Store, Video, Music and Messaging. With these tiles there is a gradient from left to right that is dark to light for both sizes of tiles. The colors listed are for the wide tile except for Sky Blue since SkyDrive only has the smaller tile.

Head on over to CreepyEd.com for the colors and codes.

Useful stuff…thanks, Ed!
