Get BBEdit HTML preview to print background colors

I realize this is probably something that only I want, but just in case, here it is for Google (and for future me, who has forgotten how to do it).

Run this in the Terminal:

[crayon-64cc3c9445a7e298046041/]

Thanks to my pal Jim Correia for figuring that out! He asked me to name a background color in his honor, so I choose “Correia Battleship Gray”.
