Category colors not rendering properly

[ltsypin]

Hello! Thank you for developing this package.

I'm having an issue where my column categories are getting assigned appropriate colors, but the row categories are not. When I look at net.viz['cat_colors'], I see:

{'row': {'cat-0': {'UMAP/Leiden: 0': '#393b79',
   'UMAP/Leiden: 1': '#ff7f0e',
   'UMAP/Leiden: 10': '#98df8a',
   'UMAP/Leiden: 11': '#404040',
   'UMAP/Leiden: 12': '#c5b0d5',
   'UMAP/Leiden: 13': '#1f77b4',
   'UMAP/Leiden: 14': '#FFDB58',
   'UMAP/Leiden: 15': '#e377c2',
   'UMAP/Leiden: 16': '#2ca02c',
   'UMAP/Leiden: 17': '#dbdb8d',
   'UMAP/Leiden: 18': '#637939',
   'UMAP/Leiden: 19': '#9c9ede',
   'UMAP/Leiden: 2': '#8ca252',
   'UMAP/Leiden: 20': '#bd9e39',
   'UMAP/Leiden: 21': '#843c39',
   'UMAP/Leiden: 22': '#d6616b',
   'UMAP/Leiden: 23': '#a55194',
   'UMAP/Leiden: 24': '#de9ed6',
   'UMAP/Leiden: 25': '#aec7e8',
   'UMAP/Leiden: 26': '#ffbb78',
   'UMAP/Leiden: 27': '#bcbd22',
   'UMAP/Leiden: 28': '#ff9896',
   'UMAP/Leiden: 29': '#8c564b',
   'UMAP/Leiden: 3': '#5254a3',
   'UMAP/Leiden: 4': '#c49c94',
   'UMAP/Leiden: 5': '#7f7f7f',
   'UMAP/Leiden: 6': '#9467bd',
   'UMAP/Leiden: 7': '#17becf',
   'UMAP/Leiden: 8': '#6b6ecf',
   'UMAP/Leiden: 9': '#d62728'}},
 'col': {'cat-0': {'phase: growth': '#393b79',
   'phase: sexual': '#ff7f0e',
   'phase: starve': '#98df8a'}}}

But the actual widget shows up like this:

This happens on both Firefox and Chrome. It's very hard for me to distinguish the shades of gray, and it would be much more useful for my data exploration if there were clear, contrasting colors. I've tried updating the hex codes myself using set_cat_color(), but that had no effect.

Could you please advise how I might fix this?

Thanks!

Hi @ltsypin, yes there is a new method for setting global category colors - you can see an example of it here on this Google Colab notebook

net.set_global_cat_colors(df_colors)

where df_colors is a DataFrame with a single column named colors and the rows are the names of categories. This coloring scheme will be used for any row/col category.
