Different colors do different things to your brain. The right glow can help you sleep faster, soothe a baby back down, or read a book without waking your partner. Night Light X gives you all of them — free.
Why color matters for sleep
The cells in your eyes that signal "it's daytime" to your brain are tuned to short wavelengths — blue and cool white light. When you're trying to wind down, that's exactly what you want to avoid. Warm tones — red, amber, soft orange — barely register on those cells, so your body keeps producing melatonin and your sleep drive stays intact.
Cool whites and blues have their place too: they keep you alert, make small text easier to read, and feel more "awake." That's why Night Light X gives you the full spectrum instead of a single fixed color — you choose what the moment calls for.

Best color for common situations
Rule of thumb: the closer to bedtime, the warmer (redder) the color and the lower the brightness. The further from bedtime — or when alertness matters — the cooler and brighter.
Pair color with sound, story, or timer
Color is just one half of a great wind-down. Layer in a sleep sound, an AI bedtime story, or an AI meditation, and set the sleep timer so everything fades together once you've drifted off.
