Warm Light
A warm, amber light that fills the screen for relaxed evenings, late reading, or winding down before bed. Warmer light carries less blue, which many people find more comfortable at night. Slide between cozy amber and neutral white and set the brightness to suit the room.
What you can use it for
- Add a warm glow to a room in the evening
- Cut blue light in the hours before sleep
- Set warm ambient lighting for photos or video
- Read by a gentle, non-harsh light

- 3. Done. No login, no install, nothing to download — it runs instantly in your browser and your settings are remembered.
Frequently asked questions
Does warm light help before bed?+
Warm, dim light emits less blue wavelength, which many people find easier on the eyes at night, so it's a comfortable choice for evening use.
Can I adjust the warmth?+
Yes. The warmth slider runs smoothly from deep amber to neutral white, and brightness is a separate control.
