Overlay violin doesn't cycle colors

[ahuang11]

groups = [chr(65+g) for g in np.random.randint(0, 3, 200)]
vio_df = pd.DataFrame({'groups': groups,
                       'value': np.random.randn(200),
                       'category': np.random.randint(0, 3, 200)})
vio_df.hvplot.violin('value', by='groups', groupby='category').overlay('category')

As written, this would go on https://github.com/pyviz/hvplot/ rather than this repo, as it's hvplot code, but maybe you know the same thing happens with regular HoloViews?

I assumed correctly :P

I believe it has to do with color not existing for Violin type?

violin.opts(color='red')

ValueError: Unexpected option 'color' for Violin type across all extensions. Similar options for current extension ('bokeh') are: ['bgcolor', 'box_color', 'colorbar'].

hv.Violin(vio_df.loc[vio_df['category'] == 0], 'groups', 'value') * hv.Violin(vio_df.loc[vio_df['category'] == 1], 'groups', 'value')

I think it's to do with the fact that you hardcoded the value as lightgray 😄

Fixed in #3593
