Matplotlib: coloring axis/tick labels

Question

How would one color y-axis label and tick labels in red?

So for example the \"y-label\" and values 0 through 40, to be colored in red.

Answer 1

  label = plt.ylabel("y-label")
  label.set_color("red")

similarly, you can obtain and modify the tick labels:

[i.set_color("red") for i in plt.gca().get_xticklabels()]

Answer 2

The xlabel can be colorized when setting it,

ax.set_xlabel("x-label", color="red")

For setting the ticklabels' color, one may either use tick_params, which sets the ticklabels' as well as the ticks' color

ax.tick_params(axis='x', colors='red')

Alternatively, plt.setp can be used to only set the ticklabels' color, without changing the ticks' color.

plt.setp(ax.get_xticklabels(), color="red")

Note that for changing the properties on the y-axis, one can replace the x with a y in the above.
