The color of ticks and tick labels can be set independently using rcParams
2+
--------------------------------------------------------------------------
3+
4+
Previously, :rc:`xtick.color` used to define the tick color and the label color.
5+
The label color can now be set independently using
6+
:rc:`xtick.labelcolor`. It defaults to "inherit" which will take the value
7+
from :rc:`xtick.color`. The same holds for ``ytick.[label]color``.
8+
For instance, to set the ticks to light grey and the tick labels
9+
to black, one can use the following code in a script::
10+
11+
12+
import matplotlib as mpl
13+
14+
mpl.rcParams['xtick.labelcolor'] = 'lightgrey'
15+
mpl.rcParams['xtick.color'] = 'black'
16+
mpl.rcParams['ytick.labelcolor'] = 'lightgrey'
17+
mpl.rcParams['ytick.color'] = 'black'
18+
19+
20+
Or by adding the following lines to the
21+
:ref:`matplotlib rc <customizing-with-matplotlibrc-files>` file: or a
22+
matplotlib style file:
23+
24+
25+
.. code-block:: none
26+
27+
xtick.labelcolor : lightgrey
28+
xtick.color : black
29+
ytick.labelcolor : lightgrey
30+
ytick.color : black
