Here are all 216 non-dithering background colors that
look the same in every browser.
Click on the color to upload the background image to
your WebTV Scrapbook.
You will see the URL of your background image
over the background image (you will see a square
patch).
To use the background:
Select the Grey page style for your page
(If you want to change the background of a page
you have already created, click on "Change page
style" on the top right and select the Grey.)
Click on "Add an item"
Click on "Text"
Type in:
Remove the 3 letters: URL (leave the quotes) and
replace with the actual URL of your background image.
Press Done.
Important Note: You will not see
the background until you publish your page. You will
probably see a grey bar in preview.
