Change Theme

Change Theme toggles Revit's interface between its Dark and Light themes in one click. It flips Revit's application UI theme, swaps every B45 Labs ribbon icon to the matching dark or light variant, and re-tints any open B45 Labs window that is set to follow the Revit theme — all without a restart. There is no dialog; the visible change is the confirmation.

1. In the B45 Labs | Coordination tab, open the Revit Settings panel and click Change Theme.
2. Revit's interface switches instantly between Dark and Light, and the B45 Labs ribbon icons swap to the matching variant.
3. Any open B45 Labs window that follows the Revit theme re-tints to match — no restart is needed.

• It is a straight toggle: each click flips to the opposite theme, so there is no separate window or setting to confirm.
• B45 windows pinned to the Plugin Theme keep their dark styling; only windows set to follow the Revit theme change with this toggle.
