make_colormap.py

from wordcloud import ImageColorGenerator

#Create the mask
colosseum_mask = np.array(Image.open('/Users/tiaplagata/Downloads/colosseum.jpg'))

#Grab the mask colors
colors = ImageColorGenerator(colosseum_mask)

#Instantiate the wordcloud using color_func argument
cloud = WordCloud(mask=colosseum_mask,
                  background_color='white',
                  color_func=colors).generate_from_text(data)

#Plot the wordcloud
plt.figure(figsize=(10,8))
plt.imshow(cloud)
plt.axis('off')
plt.title(title)
plt.show()
