BUG: set_tick_params labelcolor should apply to offset #6440
Description
The following example:
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(1,1,1)
ax.plot([1.01e9,1.02e9,1.03e9])
ax.yaxis.set_tick_params(labelcolor='red')
fig.savefig('test.png')produces the following output:
The offset label should likely be set by the labelcolor option too.
