# Second Sight

Second Sight is a browser-based colour perception test in which the player memorises two briefly shown colours and then judges whether the second one became brighter, darker or shifted in hue.

## Description

Second Sight presents a short colour perception exercise on a web page. Two colours are shown briefly, and the player has to hold the first in memory and decide whether the second appears brighter, darker or changed in hue. It is presented as a free test rather than as a game with stated rules or progression.

## Original post

Take a free colour perception test. Remember two fleeting colours and identify whether the second became brighter, darker or shifted in hue.
