Plot bar in Pandas 0.25.3 not changing the colors for each of the bars
```python
# Code
import pandas as pd
import matplotlib.pyplot as plt
import numpy as np

df = pd.DataFrame({'category': ['A', 'B', 'C'],
                   'value': [-1432.32, 10.43, 30000.00],
                   'db-id': [1234, 2424, 251]
                   })
df.category.value_counts().plot.bar(color = plt.cm.Paired.colors)
```
#### Problem description

When using the above code on pandas '0.25.3', all bars are plotted with the same color. I would like to have them plotted each with its own color. It used to work before but all of a sudden it doesnt. Possibly due to the pandas version. 
Any clue?
