More "named" colours for matplotlib before colours get recycled?

As I plot more curves using matplotlib, I see the curves/lines use the following colours and cycle around:

Can I cycle throughout more colours beyond just those 7?

You can use matplotlib's Cycler objects to interact with an underlying color-changing machinery. By creating your own cycler of desired length, you can make the turnaround as large as you want.

Here's how you can customize a color cycler to taste:

import matplotlib.pyplot as plt
food_colors = plt.cycler('color', ['tomato', 'olive', 'chocolate',
                                   'salmon', 'plum', 'lime'])
plt.rc('axes', prop_cycle=food_colors)

The snippet above sets the default color cycle to food_colors. Now all the newly drawn plots should be cycling through the six colors above.

import numpy as np
for i in range(20):
    x, y, s = np.random.normal(10, 3, size=3)
    plt.plot(x, y, 'o', ms=s*6, alpha=0.6)
plt.show()

circles

Note that if you want to change the color cycle for a given axis only, you can use ax.set_prop_cycle(food_colors) instead of changing rcParams.
