Color Signal turns your iPhone or iPad into a full-screen color display. Use a single device to show any color, or connect nearby devices over Bluetooth to keep their screens in sync. You can also create automatic color sequences or display colors captured by the camera. Use it for live events, presentations, photography, meeting points, visual cues, and any situation where a large, easy-to-see color display can help. ―――――――――― ■ Fill the Screen with Any Color Display the color you choose across the entire screen of your iPhone or iPad. Use it as a color signal at live events, an easy-to-see visual cue, a meeting-point marker, a presentation signal, and more. ・Adjust screen brightness directly in the app ・Prevent the screen from locking while in use ・Automatically hide controls for a clean, full-screen color display ・Enjoy edge-to-edge full-screen display on Mac and optimized output on external displays connected to iPhone or iPad ■ Keep Nearby Screens in Sync with Bluetooth Use Bluetooth to display the same color on nearby iPhones and iPads. Change the color on one device, and the other screens change with it. You can share manually selected colors, colors that change with the camera, and automatic color sequences. It is useful when you want multiple screens to show the same color together at events or in other group settings. ■ Intuitive Color Control Choosing a color is as simple as moving your finger across the screen. Move left or right to change the color, and up or down to adjust its brightness. You can see the result immediately and find the color you want without opening detailed settings. ■ Automatically Switch Between Colors Arrange multiple colors in any order and choose how long each color is displayed and how long the transition to the next color takes. Your colors can then change automatically according to the sequence you create. Playback can start automatically, when you tap the screen, at a scheduled time, or after a delay. Sequences can repeat continuously or play a set number of times. Ready-to-use presets such as Rainbow, Traffic Signal, and Presentation Timer are also included. Combine automation with Bluetooth sharing to play the same color sequence across multiple screens. ■ Capture a Color with the Camera Use the front or rear camera to read colors from your surroundings and display the detected color across the entire screen. You can show the detected color as it is or switch to its contrasting “opposite color.” You can also choose how colors are detected and how quickly the screen responds to changes. This is useful when you want your screen to match a color around you or quickly display a contrasting color. ■ Share Presets with QR Codes or AirDrop Share the automatic color sequences you create with other Color Signal users. Turn a preset into a QR code, and the recipient can scan it using the standard iPhone Camera app to add it to Color Signal. You can also share presets using AirDrop and other system sharing options on iPhone and iPad. ■ Camera Images Are Never Saved The camera is used only to detect colors in your surroundings. Color Signal does not save or send images or video captured by the camera. You can also use the app entirely without the camera by simply displaying colors of your choice. From a simple full-screen color display on one device to synchronized screens and automated color sequences, Color Signal gives you flexible ways to use color as a visual signal.
