Color Screen is a beautiful iOS app that provides an excellent solution for displaying a color of choice on the iPhone/iPad screen at a brightness desired. It provides a wide range of colors to choose from. It can be used in any situation that requires a colored light with adjustable brightness. You can also see the hex values and RGB values of the colors to transfer them easily to other editing softwares. The app also remembers last used color, so whenever you come back, it'll start right as you left it. Possible uses - - Use for lighting macro photography scenes with literally as bright a colored screen as your iPhone/iPad would allow. - Use as red light for star gazing. - Use strobe function with a bright color to help others (friends, family, cabs etc.) locate you easily at crowded locations (movie theatres, clubs, parties, street side etc.) - Use for design purposes to get HEX and RGB values of desired colors. - Send color codes to others via text or copy to clipboard to paste to other apps. - If you received HEX code or RGB code for a color from somebody, easily enter it in the app to see what the color looks like. Features - - Choose any color using hue, saturation and brightness sliders. - See the HEX and RGB codes of the selected color. - Update the HEX value directly to get a desired color on screen. - Update RGB value directly to get a desired color on screen. - No ads, no distraction on the screen.
