Below the fonts in the Style tab:

Colors
Pick one of the palettes, such as Sage, Blush, Dusty blue, Burgundy, Emerald & gold or Black & gold. The name of the selected palette is shown next to "Colors".
To match your own wedding colors, set them one by one:
- Text: names and titles.
- Accent: frames, ornaments and small headings.
- Background: the paper color.
A colored or dark background uses a lot of ink on a home printer. It looks best printed by a print shop.
Background
Plain, or a subtle pattern in your accent color: dots, pinstripe, grid or confetti.
Frame
None, a single line or a double line around each piece.
Ornament
The small divider under titles and names: a dot, a diamond, leaves, a flourish, or none.
Monogram
Your initials, like "E & J", filled in from your names. Change them if you like. The monogram appears where you turn it on: on card backs, at the bottom of the menu and on the welcome sign.
