Program: Input the correct color

[Truman]

# [ ] use a while True loop (forever loop) to give 4 chances for input of a correct color in a rainbow
# rainbow = "red orange yellow green blue indigo violet"

while True:
    rainbow = "red orange yellow green blue indigo violet"
    try1 = input("try color: ")
    try2 = input("try color: ")
    try3 = input("try color: ")
    try4 = input("try color: ")
    if try1 in rainbow:
        print("You guessed the colour!")
    elif try2 in rainbow:
        print("You guessed the colour!")
    elif try3 in rainbow:
        print("You guessed the colour!")
    elif try4 in rainbow:
        print("You guessed the colour!")    
    else:
        print("Better luck next time!")

I assume that this is not optimal solution. I at first tried with if try1 or try2 or try3 or try4 in rainbow: but that doesn't work. Advice is appreciated.
