How To Change Rounders Background Color (Blogger)

I believe Rounders page background is color-coded in the 'body' style
rather than selectable on F&T menu.

Dashboard, Manage:Layout, Edit Html, Download Full Template and you
will have a backup on your computer.

Changes are made right on that page, in the template editor.
The existing style might look like this:

body {
background:#bca;
(#bca is the same as #bbccaa.)

(Search this by pressing Ctrl+F or F3)

- Get the color code you want.
- On the Edit Html page you found above, slowly scroll down to the
body style, it will be near the top.
- Replace the color: a hex color code starts with #, if you use a
named color, like olive, do not include #.
- Save and view the blog.

This worked for me, i changed my mine to #000000 which is black. Hope this helps :)
