change seaborn pairplot legend alpha/color

grid = sns.pairplot(data=vst_wgcna, hue='cluster', kind="reg",
                palette=palette, corner=True,
           plot_kws={ 'scatter_kws': {'alpha': 0.05}})

grid.map_offdiag(plot_unity,  plot_kws={ 'scatter_kws': {'alpha': 0.1}})
grid._legend.set_bbox_to_anchor((0.81, 0.5))

The legend have color dots before the “positive modules" and "negative modules", because I set alpha to 0.05, it is very hard to see. how to fix that? enter image description here

As JohanC commented, we can loop through the legend handles and change their alpha:

for handle in grid.legend.legendHandles:
    handle.set_alpha(0.7)
