There is undoubtedly a more efficient way to do this, but give this a shot:
import numpy as np
import matplotlib.pyplot as plt
x = np.arange(0, 10.5, 0.5)
y = -3.0*x + 0.5*x**2
color_list = ['FireBrick', 'Orange', 'DarkGreen', 'DarkBlue', 'Indigo']
limits = np.arange(0, 11, 2)
fig, ax1 = plt.subplots()
for n, color in enumerate(color_list):
lower = np.where(x >= limits[n])[0]
upper = np.where(x <= limits[n+1])[0]
index = np.intersect1d(lower, upper)
ax1.plot(x[index], y[index], linestyle='-', color=color, linewidth=2)
plt.show()
