Open a quiz → Create → the Brand card, the last card in Create.
Brand is set per quiz, not per account, so each offer can look like the brand behind it. It's available on every plan, including Free.
Logo — PNG, JPG or WebP, up to 1 MB. SVG isn't supported. Your logo appears centered above the title on the start screen, and small in the top left of every question, the capture step and the result. A quiz with no logo looks exactly as it does today — nothing is reserved or shifted.
Primary color — pick one of the eight swatches, type a hex value (#2563eb or the short #abc form), or use the color picker. This becomes the buttons, the progress bar, the selected-answer highlight, links and focus rings.
Accent (optional) — used for highlights. Leave it empty and it's derived from your primary color.
Contrast warning — if neither white nor near-black text is easy to read on your primary color, you'll see "Text on this color may be hard to read. Try a darker or lighter shade." It's a warning only; you can still save.
Preview — the small start-screen preview inside the card updates as you pick colors, and the full Preview button shows the whole quiz with your brand.
Reset to QuizFly default clears the logo and both colors, and the quiz goes back to the standard QuizFly look.
Your brand shows everywhere the quiz runs: quizfly.app, your own custom domain and inside an embed.
The QuizFly badge in the quiz footer is a separate thing: removing it is a paid-plan feature. See Plans and what's included.
Next: The builder.
In the Wizard. Step 6, Make it yours, shows the same card with the logo and your main color; the accent color is derived for you and can be changed later in the builder.
