Code to reproduce issue

import eta.core.annotations as etaa

import fiftyone as fo

mask_path = "mask.png"
seg = fo.Segmentation(mask_path=mask_path)

polylines = seg.to_polylines({1: "smoke", 2: "fire"})

im_path = "image.jpg"

sam = fo.Sample(filepath=im_path)
sam["segmentation"] = seg
sam["polylines"] = polylines
ds = fo.Dataset()
_ = ds.add_sample(sam)
colormap_config = etaa.ColormapConfig(
    {
        "type": "eta.core.annotations.ManualColormap",
        "config": {"colors": [
            "#a6cee3", "#1f78b4", "#b2df8a", "#33a02c",
            "#fb9a99", "#e31a1c", "#fdbf6f", "#ff7f00",
            "#cab2d6", "#6a3d9a", "#ffff99", "#b15928"
        ]},
    }
)
ds.draw_labels("label_out", label_fields="polylines", colormap_config=colormap_config,
               per_polyline_label_colors=True,
               per_polyline_name_colors=True
