Do you think you can distinguish colors easily? A new online test is showing that color perception is much more complicated than it seems.
The test called "Hue Shift" confronts users with a seemingly simple challenge: to match two color shades in just 10 seconds.
The rules are minimal. Two blocks of color appear on the screen. One remains unchanged, while the other must be adjusted until it matches the first as closely as possible. With a swipe on the screen, the user changes the tone and brightness of the color.
There is only 10 seconds of time in each round, while a countdown appears in the final seconds to add pressure. After each attempt, an error rating is given: the lower the score, the more accurate the match.
At the end of the test, a final score called “delta–E” is displayed, a measurement that shows how close the efforts were to the real color. The lower this number, the better the ability to distinguish shades.
The test was created by software engineer Keith Cirkel, who has developed several other color-based games. It went viral due to the simplicity of the rules and unexpected difficulty.
According to the game's description, the control system takes some time to learn, but then results quickly improve with practice.
If performance is poor, the game suggests that it takes “a little practice to understand the color and brightness axes.” For the best results, it emphasizes stable control and the ability to immediately distinguish subtle changes.
For those who like this challenge, Cirkel has created another test known as "What's My JND?", where players try to find the minimum boundary between two colors - that is, the smallest difference that the eye can distinguish. /GazetaExpress/
