Very basic if in Python [duplicate]

Just trying my first piece of code doing the exercise 36 in LPTHW. I'm supposed to create a basic game but I run into a problem with the first conditional. Whether I input red, green, blue or any other thing I get the function that is supposed to run only when red is entered:

player = input("Welcome to The Hall! What's your name? > ")

def hall():
    hallDoor = input(f"""Welcome to The Hall {player}! There are 3 doors in front of you, which one will you choose?
    - Red door
    - Green door
    - Blue door
> """)

    if "red" or "Red" in hallDoor:
        monster1()
    elif "green" or "Green" in hallDoor:
        monster2()
    elif "blue" or "Blue" in hallDoor:
        god()
    else:
        print("Pick a color")
        hall()

def monster1():
    print("Meet Neil!")
    exit(0)

def monster2():
    print("Meet Brad!")
    exit(0)

def god():
    hall() 

hall()

I've been trying to figure it out for a while but can't. I'm using Reapl.it.
