Description
Bug summary
When a colorbar hasextend != 'neither', the triangles at the end of the colorbar always havealpha=1, even when the rest of the colorbar has a different alpha value.
Code for reproduction
#!/usr/bin/env python3# -*- coding: utf-8 -*-importnumpyasnpimportmatplotlib.pyplotaspltimg=np.random.rand(5,10)alpha=0.5plt.subplot(1,2,1)plt.imshow(img,alpha=alpha,cmap='RdBu')plt.colorbar(extend='both',orientation='horizontal',label='Current behaviour')# Temporary fix to manually set the alpha of the extend patches# doesn't look perfect, but is an improvement over the current behaviourplt.subplot(1,2,2)plt.imshow(img,alpha=alpha,cmap='RdBu')cb=plt.colorbar(extend='both',orientation='horizontal',label='Temporary fix')forpatchincb._extend_patches:patch.set_alpha(alpha)plt.show()
Actual outcome
Expected outcome
The triangles at the end of the colorbar should have the same alpha as the colorbar (i.e. roughly like the temporary fix above)
