Screen Light Color is a free iPhone app developed by Brian Li Sui Fong that transforms your device's display into a simple light panel with no on-screen distractions. With this app, you can easily adjust the color of the light to suit your needs.

Whether you're a photographer in need of a basic studio light panel, an artist looking for a light table for drawing and tracing, or someone who wants a night light or flashlight, Screen Light Color has got you covered. It can also serve as a reference for color-matching, a red light for night strolling or star-gazing, a beacon and visual signal, or even a mood light.

In addition to the free features, there is an in-app purchase available that unlocks precision sliders for white balance, allowing you to achieve the perfect warm or cool color temperature. You can also save color swatches for later use and control a larger light panel on your TV or external display using AirPlay or a cable connection.

With its versatility and user-friendly interface, Screen Light Color is a handy utility for a variety of purposes.
