Colorbolt vs Screen Light App

Colorbolt turns your phone into a full-screen color Swiss Army Knife. Pick a color and swipe anywhere on the screen to control the actual brightness of your device. Use it as a fill light for photos, a mood lamp, a concert lighter, a nightlight, to sneak into bed without waking anyone, or just because it looks good. PREMADE PALETTES • 30 curated colors across three palettes — Basics, Vibes, and Moods. Useful, atmospheric, and very attractive. THREE ONE-TAP MODES • Global Pulse — Every Colorbolt pulses once per second in perfect sync and shares the same slowly drifting color. No pairing or setup. Great for concerts and festivals. • Pulse — Your chosen color rises and falls on a steady once-per-second pulse. • Rainbow — A smooth, authored 12-second journey through the full color spectrum. CUSTOM COLORS • Color wheel — Drag to any hue and saturation. • Kelvin temperature slider — Dial in warm candlelight at 1800 K or crisp daylight at 6500 K. • RGB + HEX entry — Find values from the colors, or colors from the values. • Save your favorites — Build a personal library of colors you love and use. HOME SCREEN WIDGET Access fullscreen colors directly from your home screen — white, red, your last used color, or a shortcut straight to the color picker. No ads. No in-app purchases.
