The colors of the elements do not respect the frequency of light. Check the colors of the rainbow out, there you would see that the purple is in highest position.
Considering that this game follows the inversion of the reality that one can observe in our reality, the red color is in the lower position (without adulteration); then, the yellow is the color for the leaver (check Prometheus mith), which is considered the false light. After that, it comes the color of the heart: the green color. The heart is the home of compassion, love and truth. These vibrations are in the opposite side of the purpose of this game.
The game approaches the spiritual reality. There’s no doubt it does. At the same time, it says that they won’t observe high spiritual lessons. If you’re looking for that, you landed on a very wrong soil.
Therefore, the developers feel free to spread all the kinds of dark symbolism.
Definitely, it’s meant to enslave your mind not to free your spirit.
