Colour Blindness Test

Colour Blindness Test is a screamer video uploaded to YouTube by user Ashwani Srivastava.

The video has the viewers participate in a challenge, where they must select the correct answer for which number is being shown in a color blindness test; it claims that a special score will be given at the end. However, after the seventh item is completed, a picture of Regan MacNeil from The Exorcist pops up along with the same screams from The Maze.
