You probably want ax.spines.set_color()

These will give you a broad range of options for custom solutions:

ax.spines['bottom'].set_color('0.5')
ax.spines['top'].set_color(None)
ax.spines['right'].set_color('0.5')
ax.spines['left'].set_color(None)
ax.patch.set_facecolor('0.1')
plt.grid(b=True, which='major', color='0.2', linestyle='-')
plt.grid(b=True, which='minor', color='0.2', linestyle='-')
ax.tick_params(axis='x', colors='0.7', which='both')
ax.tick_params(axis='y', colors='0.7', which='both')
ax.yaxis.label.set_color('0.9')
ax.xaxis.label.set_color('0.9')
ax.margins(0.5)
fig.patch.set_facecolor('0.15')
