Color Flashlight – ScreenFlash app icon Color Flashlight

The color flashlight that turns your iPhone into any light you need

Your LED flash only does white. Color Flashlight – ScreenFlash uses your whole screen to shine any RGB color — a mood light, party strobe, SOS beacon, night light and photography fill light in one free app.

How it works

Any color light in four taps

No account, no setup. ScreenFlash uses your display — bigger, softer and cooler-running than the LED flash — so the perfect light is seconds away.

1

Tap the power button

Open the app and hit the big power button — your screen ignites instantly at your last color and brightness.

2

Pick your color

Drag the color wheel or fine-tune Red, Green and Blue sliders. Jump to Warm, Cool, Pastel, Neon or Cinematic palettes in one tap.

3

Add an effect

Swipe up for Strobe, SOS, Disco, Police and Rainbow. Long-press any effect to adjust speed and looping.

4

Save your preset

Keep unlimited favorites — your reading amber, party strobe or baby night light is always one tap away.

Features

A complete color light toolkit

🎨

Unlimited RGB colors

Full-spectrum color wheel plus individual R/G/B sliders and color-temperature control for the exact tint you need.

⚡

Adjustable strobe light

50–1000 ms flash timing for parties, cycling visibility or photography — far more control than LED strobe apps.

🆘

SOS Morse beacon

One tap flashes the international ··· ––– ··· distress pattern, meeting global emergency signaling standards.

🪩

Disco & Rainbow modes

16-color disco jumps with vibration sync, or a smooth rainbow hue rotation for ambient color.

🚨

Police lights

Authentic alternating red-blue pattern that boosts roadside visibility or powers your costume and party effects.

🌙

Night light & dimmer

Dim from floodlight to gentle baby-nightlight and lock the brightness — with a dark, glare-free interface.

🎬

Timeline editor (Pro)

Script multi-step color shows with fade, hold, pulse and loop — an industry first for light apps.

🔋

Battery & heat smart

Screen light runs cooler than a strobing LED, and the wakelock keeps the display on only while you need it.

iPhone & iPad

Universal app for iOS 12+ — the bigger the screen, the bigger your light.

FAQ

Frequently asked questions

Can you change the flashlight color on an iPhone?

How do I make my iPhone screen red at night?
