You can get a list of tick labels using ax.get_xticklabels(). This is actually a list of text objects. As a result, you can use set_color() on an element of that list to change the color:

import matplotlib.pyplot as plt

fig, ax = plt.subplots(figsize=(5,4))
ax.plot([1,2,3])

ax.get_xticklabels()[3].set_color("red")

plt.show()

Alternatively, you can get the current axes using plt.gca(). The below code will give the same result

import matplotlib.pyplot as plt

plt.figure(figsize=(5,4))
plt.plot([1, 2, 3])

plt.gca().get_xticklabels()[3].set_color("red")

plt.show()
