colorbar set_ticklabels - text properties not working

[trafra99]

Bug report

Bug summary

Unable to set label color or other text properties

Code for reproduction

from mpl_toolkits.axes_grid1.inset_locator import inset_axes

fig, ax = plt.subplots(figsize=(5,6),dpi=200)

#hiding the axis numbers
ax.axes.xaxis.set_visible(False)
ax.axes.yaxis.set_visible(False)

#setting the axis dimensions
ax.set_xlim((-250, 250))
ax.set_ylim((422.5, -47.5))

#setting the background color as black ('k') for a better visualization
ax.set_facecolor('k')
fig.set_facecolor('k')

cbaxes = inset_axes(ax, width="5%",  
               height="50%", 
               loc='lower left',
               bbox_to_anchor=(.7, 0.07, 5, .08),
               bbox_transform=ax.transAxes,
               borderpad=0,
               )
bar_palette = mpl.cm.inferno
bar = mpl.colorbar.ColorbarBase(cbaxes, cmap=bar_palette, orientation='horizontal')

# creating ticks 
bar.set_ticks([0,1])
bar.set_ticklabels(ticklabels=['Low', 'High'], color='white')

Actual outcome
TypeError: set_ticklabels() got an unexpected keyword argument 'color'

Expected outcome
I need the labels to be white because the background is black
IMPORTANT
If you put 'white' instead of 'k' in ax.set_facecolor('k') and remove color='white' from bar.set_ticklabels
you can see that the labels are properly created, but they are black and apparently there is no way to make them
change.

Thanks to anyone who can help!

Yes, set_ticklabels should probably pass kwargs down to the base axes. #20054 is meant to make this easier, though this particular case has not been addressed yet.

In the meantime, you can do bar.ax.xaxis.set_ticklabels(...) and it will work as you expect.

As an aside, you might consider the core:

cbaxes = ax.inset_axes([0.7, -0.075, 0.3, 0.03]) 
bar = fig.colorbar(mappable, cax=cbaxes)

though perhaps you do not have a mappable?

Thanks for the reply! Unfortunately I do not have a mappable, I'll stick to your solution, it works as a charm.
