sun-screen is a web app to improve the lighting in home office or conference video calls. In a dual monitor setup, on one screen you can run the video call, while the second monitor improves the lighting of your face. You can also use it as background light.
It works by using the computer or device screen to emulate various natural sky conditions (high noon sunlight, overcast, clear blue sky) and artificial light bulbs (incandescent, fluorescent and others). It fills the full screen background of the browser window with their representations in the RGB color space. You can slide between two colors to adapt for lighting changes during the day.
