The post discusses an online color perception test where users must identify an odd disk among similar ones based on color. User comments reveal varying levels of success, with scores ranging from 15 to 20 out of 20. Many users note that certain disks are harder to differentiate, particularly in lower saturation or shades of red, which may also depend on individual screen calibration and color accuracy. One common observation is that prolonged focus on a disk can distort color perception, reminiscent of visual phenomena experienced during events like eye migraines. The creator of the test invites participants to share their experiences and score to contribute to a future video related to color perception.
