having an issua comparing comparing Strings @ python

Probably there is an easier way to do this, but i read there is no Switch/case in Python. I wanted to ask the user, to introduce a name of a color, and after calling the function that should take care of that, it should return the color code in RGB. My if statements should also accept when the first letter or the whole word is in capital.

The wierd thing that is happening to me is, i keep geting results on my console that makes no sence, i am SURE that there is (somewhere) a mystake from me!

After puting the same input, exacly the same word, the results on the console are not the same.

AT the moment this is my exact code.

import pygame
import sys

from pygame.locals import *

White =(255, 0, 0)
Black = (0, 0, 0)

Red = (255, 0, 0)
Green = (0, 255, 0)
Blue = (0, 0, 255)

Yellow = (255, 255, 0)
Cyan = (0, 255, 255)
Purple = (255, 0, 255)


def set_display():
    pygame.init()
    Display = pygame.display.set_mode((400, 300))
    pygame.display.set_caption('Seda\'s drawing game')


def get_color():
    print('Please introduce one of the following colors')
    print(' \n White \n Black \n Red \n Green \n Blue \n Yellow \n Cyan \n Purple')
    color = input()
    print (color)
    if (color == 'Black') or (color == 'BLACK') or (color == 'black'):
        return Black
    elif (color == 'White') or (color == 'WHITE') or (color == 'white'):
        return White
    elif (color == 'Red') or (color == 'RED') or (color == 'red'):
        return Red
    elif (color == 'Green') or (color == 'GREEN') or (color == 'green'):
        return Green
    elif (color == 'Blue') or (color == 'BLUE') or (color == 'blue'):
        return Blue
    elif (color == 'Yellow') or (color == 'YELLOW') or (color == 'yellow'):
        return Yellow
    elif (color == 'Purple') or (color == 'PURPLE') or (color == 'purple'):
        return Purple
    elif (color == 'Cyan') or (color == 'CYAN') or (color == 'cyan'):
        return Cyan





while True:

#    set_display()
#    for event in pygame.event.get():
#       if event.type == QUIT:
#           pygame.quit()
#           sys.exit()


    final_color = get_color()
    print ( get_color())
    print (final_color)

Console output:

it seems every 2 times i write something, if gives me back the color RGB code.

what i keep finding hard to understand, is why this:

    final_color = get_color()
    print ( get_color())
    print (final_color)

is not showing the exact same thing.

Thanks for the help guys

EDDIT1: i found out using extras on those prints, that he is not getting to those 2 last prints. Still to know why..
