How can I change colors in subplots?

You can change colors in subplots by using the set_facecolor method or by specifying colors in the plot function.

Can you show me an example of how to do that?

Sure! Here's a simple example:

import matplotlib.pyplot as plt

fig, axs = plt.subplots(2)

axs[0].plot([1, 2, 3], color='red')  # Change color of the first subplot
axs[1].plot([1, 2, 3], color='blue')  # Change color of the second subplot

plt.show()

What if I want to use a gradient color?

For gradient colors, you can use the imshow function with a colormap. Here's an example:

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 1, 100)
y = np.linspace(0, 1, 100)
X, Y = np.meshgrid(x, y)
Z = X + Y

fig, ax = plt.subplots()
ax.imshow(Z, cmap='viridis')  # Using a gradient colormap
plt.show()
