This app covers the entire screen from the moment you start the test. This allows you to control all pixels. Every time you touch the screen, 3 primary colors (Red, Green, Blue) and 4 secondary colors (Fuchsia, Cyan, Yellow and Black) and White color, which are their derivatives, are displayed sequentially on the screen. Once the colors start appearing, you need to carefully examine the entire screen and check if there is a pixel that does not give the displayed color. If you do not encounter any problems, you can tap the screen again to move to the next color. When the test is finished, the application asks whether you want to repeat it and starts again or returns to the main menu depending on your answer.
