/f/<name>, the booking page at /book/<name>, and the form when it is embedded in a page of your own.
Colour scheme
The default is Light. A hosted form is the business’s page rather than the visitor’s app, so it does not inherit the dark mode your dashboard might be in — and Match visitor is something you opt into rather than something that happens to you.
Accent colour
Twelve presets — Violet, Indigo, Blue, Cyan, Teal, Green, Lime, Amber, Orange, Red, Pink and Slate — plus a colour picker and a box you can type a hex value into. The value must be a full six-digit hex such as#0d9488; a half-typed one is simply not applied yet.
The accent drives the header banner, the submit and Next buttons, the selected state on radio and checkbox rows, the progress bar and every focus ring.
The text on an accent-coloured button is set to black or white automatically, whichever reads better against the colour you picked. A pale yellow accent gets dark text rather than white-on-yellow.
Header
The form’s name and description are shown in the banner. With None they sit at the top of the card instead, so the page always says what it is.
The description comes from the Settings tab. A booking form also carries a Book a time line above the title.
Corners
Sharp, Soft or Pill — the rounding on inputs, buttons and the card itself. Soft is the default.Branding
Hide “Powered by” removes the Powered by Watx line under the form card.Previewing
There is no separate preview to open: the canvas in the middle of the Build tab is the form on its real page background, banner and branding included. Changing the accent repaints it as you click. Turn on Try it above the canvas to type into the fields and walk through the steps as a visitor would. Submitting stays disabled in the builder.1
