  description: |
    **Occupancy and Light Level Automation for Third Reality Lights with Color Control**

    This blueprint automatically controls a Third Reality light based on:
    - **Occupancy detection**: Light turns on when motion/occupancy is detected
    - **Light level**: Only turns on when ambient light is below the threshold
    - **Color selection**: Choose your preferred color via color picker
    - **Timeout**: Turns off after a configurable period of no occupancy

    Perfect for hallways, bathrooms, closets, and other areas where you want automatic lighting that respects ambient light conditions with custom colors.

    **Requirements:**
    - Motion/occupancy sensor
    - Light/illuminance sensor  
    - Third Reality light (or any RGB-compatible light)
