Themes
What it is
A theme restyles your whole mind map in one click — bubble colors, text color, font, connector line color, and the canvas background — using one of our built-in presets.
What it's for
You can use a theme to quickly give your map a polished, consistent look for presenting or sharing, without hand-coloring every bubble yourself.
How to open the theme gallery
You can open it in three ways:
- Click the color-wheel Theme button in the bottom-right corner of the editor.
- Right-click any empty area of the canvas background → Theme…
- Open the Mind Map menu on the toolbar → Theme…
All three open the same gallery of presets, each shown as a small preview of its colors, font, and background.

How themes behave
- Undo/redo works — if you don't like the result, undo brings your map right back.
- They're saved with your map and shared live with collaborators — anyone viewing the map sees the theme change as it happens.
- Anyone who can edit the map can change its theme — it isn't limited to the map's owner.
- They appear in exports — themed colors and backgrounds show up when you save or export the map to an image or PDF.
- New bubbles keep matching. Any bubble you add after applying a theme automatically picks up that theme's colors, so your map stays consistent as it grows.
Good to know (current limitation)
- Applying a theme replaces any custom colors or fonts you'd already set by hand on individual bubbles or lines — it bakes the new theme's look into the whole map. If you want to keep some bubbles custom-colored, re-apply your custom color after picking a theme.
- Bubble shape (round, for example) doesn't change between presets right now — themes currently only vary color, font, and background.
Quick tips
- Try a few presets before settling — applying one is instant and undoable, so there's no harm in experimenting.
- Presets with a dark canvas background (like Midnight or Blueprint) work well for presentation mode.
- If you're presenting to an audience, pick a theme before you start — it'll look consistent from the very first bubble.
