3. Key Features and How to Use Them
f.lux provides several features to help reduce blue light exposure and customize your screen’s appearance. Here’s how to use some of its key features:
- Automatic Color Adjustment: f.lux automatically adjusts your screen's color temperature based on your location's sunrise and sunset times. During the day, the screen will be cooler and brighter, while at night, it will reduce blue light and become warmer.

- Darkroom Mode: For extreme low-light environments, f.lux offers ‘Darkroom Mode,’ which turns your screen red and black. This mode is ideal for working at night or in very dark environments. Enable it via the f.lux menu.
- Adjust Transition Speed: You can control how fast f.lux transitions between day and night modes by going to ‘Settings’ and selecting ‘Adjust Transition Speed.’ Choose from ‘Very Fast,’ ‘Fast,’ ‘Medium,’ or ‘Slow.’

5. Troubleshooting Common Issues
Here are some common issues you may encounter with f.lux and how to resolve them:
