GeoPandas: How to plot hexagon geometry?

I have a geopandas dataframe with hexagon geometry and a label and I am having trouble figuring out how to:
- plot the hexagons with my own color scheme
- show the legend
a snippet of the data looks like:
geometry pred_labels color
0 POLYGON ((63.06967 29.61571, 63.07798 29.60487... 1 0.000000
1 POLYGON ((63.18163 29.99343, 63.18998 29.98255... 3 0.666667
2 POLYGON ((62.99624 29.69126, 63.00458 29.68042... 1 0.000000
3 POLYGON ((63.32191 29.58779, 63.33018 29.57693... 1 0.000000
4 POLYGON ((63.64046 29.59359, 63.64869 29.58271... 1 0.000000
10509 rows × 3 columns
when I plot:
df_january.plot(cmap='Purples', legend=True);
I get something that appears right, but if I specify column to pred_labels or color, I will get very wonky and messed up plots. For instance:
df_january.plot(column='pred_labels', cmap='Purples', legend=True);

Following J.Warren, placing the geometry column at the end of the df improved plotting.
