Are You Colourblind?
From Screamer Wiki
Are You Colourblind? is a flash screamer. It pretends to be a colourblind test, but after clicking on the enter button on the third question a flashing picture of an conjuct eye pops up with a chaotic scream and the sound of electricity. After that, the text "YOU ARE COLOURBLIND" flashes for 1 second. Than the screen shifts to the credits with the words "YOU LOSER!!!!!!!!!!!" as well as a replay button.
