Python: Simple Color Mixer

This is work completed for an assignment for Ashford University's CPT200: Fundamentals of Programming Languages

Problem:

The colors red, blue, and yellow are known as the primary colors because they cannot be made by mixing other colors. When you mix two primary colors, you get a secondary color, as shown here:

• Red and blue = purple
• Red and yellow = orange
• Blue and yellow = green

#Note: The assignment called for lists to be used but I opted for a tuple because I don't think the primary colors are changing any time soon. 

Script:

primary_colors = ('red', 'yellow', 'blue')

user_input = ''

print('*******************************************')

print('*                                                         *')

print('*      Welcome to the Color Mixer!      *')

print('*                                                         *')

print('*******************************************\n')

def get_color(ordinal):

    color = input(f'{ordinal} primary color: \t').lower()

    if color in primary_colors:

        return color

    else:

        print('Invalid entry, please enter red, yellow, or blue')

        return get_color(ordinal)

def mix_colors(color1, color2):

    print('\nMixing colors...')

    if color1 == color2:

        return color1.capitalize()

    elif (color1 == 'red' and color2 == 'blue') or (color1 == 'blue' and color2 == 'red'):

        return 'Purple'

    elif (color1 == 'yellow' and color2 == 'blue') or (color1 == 'blue' and color2 == 'yellow'):

        return 'Green'

    else:

        return 'Orange'

def display_results(color1, color2, mixed_color):

    print(f'{color1.capitalize()} and {color2.capitalize()} = \t{mixed_color}\n')

def keep_going():

    global user_input

    try: 

        user_input = input("Enter 'q' to quit or press any other key to continue mixing colors: \t")[0:1].lower()

    except:

        print('Invalid entry!')

        keep_going()

while user_input != 'q':

    print('\nPlease enter two primary colors (red, yellow, blue).')

    color1 = get_color('First')

    color2 = get_color('Second')

    result = mix_colors(color1, color2)

    display_results(color1, color2, result)

    keep_going()

else:

    print('Goodbye!')

Results:

Ideas for Rework and expansion:

• I like the idea of importing colorama and formatting the output so that there is some actual color involved. 
• I've seen this done using dictionaries and lists for comparison, could refactor it to accomodate that. 

Hope this helps, leave me feedback if you'd like to see something specific!
