Branding & themes

Your deck has a look, and Doppio's charts are built to sit comfortably inside it. Polls look great out of the box, and a small set of theme controls covers everything from a classroom to a conference stage.

Palettes

Open Colours & Theme in the poll editor and pick a palette. The palette sets the colours of your chart's bars: each new answer option takes the next colour in the set. Want one option to stand out? Override its swatch on the answer card and the rest of the palette stays put.

Chart backgrounds

Choose how the chart sits on your slide:

• Match Palette. The background takes a complementary tone from your chosen palette. The low-effort, good-looking default.
• Custom Colour. Pick an exact colour. Handy when your slides use a specific brand background.
• Transparent. No background at all, so the bars float directly on your slide design. Lovely on decks with textured or image backgrounds.

Set it once per event

When you create an event, the Default Theme section lets you choose a palette and chart background up front. Every poll you add to that deck starts from those defaults, so your fifth poll matches your first without any fiddling. Any individual poll can still go its own way afterwards.

Check it from the back row

Before the big day, present to yourself once and look at the chart from a few metres back. Strong contrast between bars and background is what keeps results readable under a venue projector.
