Can I customize themes in Blender?
Summary
Q.Can I customize themes in Blender?
A.Yes — Blender lets you fully customize the UI theme (colors, sizes, and editor-specific settings), save and install theme presets as XML files, and use community add‑ons to automate or extend theme behavior.

Yes — Blender includes a built‑in Themes panel (Preferences → Themes) that lets you change colors and small UI details per editor, save your custom theme as a preset, and install XML theme files from disk. The official Blender manual explains the Themes section and the preset management buttons (Add, Save, Install, Reset) so you can edit colors in real time and store your adjustments as a reusable theme. Blender manual — Themes
In practice you can: - Edit colors per editor (3D View, Outliner, Node Editor, etc.) and tweak things like dot sizes and highlights. - Save a theme to an XML preset (Blender writes it under scripts/presets/interface_theme/) and install or remove themes from the same Preferences panel. For common OS paths and manual copying of saved XML files see community notes. Blender Stack Exchange — exporting/importing themes
If you want extra behavior (for example auto‑switching light/dark themes with your OS), community add‑ons are available on the Blender Extensions platform. These let you pick light and dark presets and apply them automatically at startup. Blender Extensions — Auto Switch Theme
