ChromeTones — Blue Light & Dark Mode Scheduler

ChromeTones — Blue Light & Dark Mode Scheduler Your screen doesn't have to wreck your sleep or strain your eyes. ChromeTones gives you scientifically-grounded display filters that go far beyond a basic night mode — with smart scheduling that does the work for you. 🖥️ 7 POWERFUL FILTER MODES Blue Light Filter — A warm amber overlay that neutralizes harsh blue light emissions. Adjust intensity from a subtle warmth to a deep amber glow. Perfect for evening browsing without the eye fatigue. Dark Mode — Instantly inverts and dims any webpage into a comfortable dark theme. Works on every site, even ones that don't offer their own dark mode. Great for late-night reading and OLED-friendly browsing. Sleep Prep — Our most advanced filter, purpose-built for bedtime. Aggressively targets the 480nm blue light wavelength that suppresses melatonin production. Use it 1–3 hours before sleep to help your body wind down naturally. Color temperature drops from ~4500K all the way down to ~1900K at full intensity — warmer than candlelight. Reduce Eye Strain — A subtle, intelligent warmth that tames the harsh LED blue spike modern monitors produce, shifting from 6500K toward a gentler ~4800K. Keeps colors accurate while eliminating that "my eyes are burning" feeling during long work sessions. Reader Mode — Mimics the look of warm paper with a low-contrast sepia tone. Reduces glare and contrast fatigue during long articles, research papers, or ebook reading. Like putting on reading glasses for your screen. Grayscale — Strips color from the screen to reduce dopamine-triggering design patterns. Choose anywhere from subtle desaturation to full grayscale. A simple but powerful way to cut screen addiction and stay focused. Color Blind Assist — Real Daltonization correction based on peer-reviewed Viénot, Brettel & Mollon simulation models. Supports Protanopia (red-blind), Deuteranopia (green-blind), and Tritanopia (blue-blind). Shifts colors you can't perceive into channels you can — making the web more accessible. 🔀 Combine Filters — Mix any two filters together with a custom blend ratio. Want Sleep Prep plus Dark Mode? Blue Light with Reader Mode? Dial in the exact combination that works for your eyes and your environment. 🕗 SMART SCHEDULING Manual Schedule — Set your own start and end times.
