In Portal, what color is the Morality Core?

The Morality Core in the video game Portal is represented by the color purple. This is because the color purple is often associated with wisdom, creativity, and introspection. In the game, the Morality Core is responsible for influencing the artificial intelligence of the main antagonist, GLaDOS, towards more moral decision-making. This color choice helps to emphasize the importance of ethical behavior and thoughtful choices when it comes to artificial intelligence, serving as a visual cue for players to consider the moral implications of their actions in the game.
