Well there are also screenshots that show the Beta Refresh in a black color. They have a selectable color on this refresh. The site i seen showed the Royale, Silver and Black colors.
I should be getting this email to download it soon. After i do i can confirm or deny the color change ability since i am a part of this Beta.
Well it is offically out. I am currently downloading it. I will let you know after i get it installed.
