Color Sensitivity Test

The human retina contains three types of cone cells, which are most sensitive to red, green, and blue light wavelengths respectively. The coordinated work of these three types of cells allows us to distinguish millions of colors. However, everyone's color perception ability varies, which is not only influenced by genetic factors but also related to acquired eye habits and age.

This test aims to assess your color sensitivity. In the test, you need to find the block with a different color from a group of similarly colored blocks within a given time. As the level increases, the number of blocks will gradually increase (starting from 2x2, up to 10x10 or more), and the color difference (Delta value) between different blocks will become smaller and smaller, making the difficulty increase exponentially.

If you find it difficult to distinguish certain specific colors during the test, or struggle at lower levels, this may suggest a certain degree of weakening in your cone cell function or a slight tendency towards color weakness. If you wear glasses, please ensure that the lenses are clean and free of severe scratches or color casts, as this will also affect your test results.
