LogoTone is a free browser game built around one simple idea: you probably do not remember the exact color of your favorite brands as well as you think you do.
Each round shows a grayscale logo and three sliders for hue, saturation, and brightness. Submit your guess and see how close your memory is to the real brand color using the CIEDE2000 Delta E color distance formula.
Explore more than 100 brands across tech, food, automotive, fashion, finance, gaming, streaming, and sports. Share your score and challenge your friends.
