Colored Icons to use in a palette

colored_dots.py

# A simple function that uses python3 and matplotlib, and creates a plain colored circle (transparent png image 500x500 px).
# Inputs are the color_list and and the name of the file. 
# The color_list can include multiple colors. A single color create a circle with that color. 
# Multiple colors create a circle divided equally by the sum of the colors

# my_dpi variable is needed in order to make matplotlib to print an image with a specific size (usually dpi=96).

import matplotlib.pyplot as plt

def draw_colorbuttons(color_list, color_name):
    my_dpi=96
    filename = color_name + ".png"
    parts_of_button = []
    for i in color_list:
        parts_of_button.append(10)
    
    fig1, ax1 = plt.subplots(figsize=(500/my_dpi, 500/my_dpi), dpi=my_dpi)
    fig1.subplots_adjust(0,0,1,1)
    ax1.pie(parts_of_button, colors=color_list)
    ax1.axis('equal')
    plt.margins(0,0)
    plt.savefig(filename, transparent=True)
    
    # remember to plt.show() after making the pictures/plots because the images stay loaded. 
    # If you have multiple plots showing and you are unable to close them all use plt.close('all')
