@story645 - I know you initially mentioned having two examples, but I ended up making just one example to illustrate how label and color could be used, while also addressing how to hide a label. Let me know if you think we still need another example.

import matplotlib.pyplot as plt

fig, ax = plt.subplots()

fruits = ['apple', 'blueberry', 'cherry', 'orange']
counts = [40, 100, 30, 55]
bar_labels = ['red', 'blue', '_red', 'orange']
bar_colors = ['tab:red', 'tab:blue', 'tab:red', 'tab:orange']

ax.bar(fruits, counts, label=bar_labels, color=bar_colors)

ax.set_ylabel('fruit supply')
ax.set_title('Fruit supply by kind and color')
ax.legend(title='Fruit color')

plt.show()

I think the image is gonna read super well as a gallery thumbnail, so I love that. I am a little worried that it's doing a lot, but that's probably solvable in comments or w/ the simpler case added but this as the thumbnail.

ETA: or leave it be and if we get too many questions about the simpler case, add it then.
