Colour choice

Confront a screen adorned with 16 colored squares, featuring four distinct colors: red, blue, green, and yellow. A single tap initiates the game, causing the background color to rapidly blink in one of the four hues. Your task is to swiftly select a square matching the displayed color to eliminate it. Choosing a square of a different color results in a loss. Continue until every square is removed, achieving victory when all squares are successfully cleared. Strive for speed to attain a lower final record time!
