I figured it out--<Shift + color-letter> changes the background color!

Shift+w = white background

Shift+9 = dark gray background

Shift+d = black background

Also I found out the color letters aren't limited to "rgbyo", there's a color for nearly every letter.

d = black

w = white

u = umber (nice brown)

i = teal

p = cream

s = salmon

l = slightly muted yellow
