Slim supports displaying segmentations with multiple segments, but they all display with the same color (yellow). It would be better if they displayed with multiple colors so that you can toggle on multiple non-overlapping segments and see the distributions of each segment over the image.

Even better I suppose would be to have the colors configurable in the UI and/or follow the (optional) color hints in the segmentation files (RecommendedDisplayCIELabValue within the Segment Sequence).

Good sample data would be the transcriptional subtypes from this bucket: https://console.cloud.google.com/storage/browser/transcriptional_subtypes_2025-03-03;tab=objects?forceOnBucketsSortingFiltering=true&inv=1&invt=Ab3nvw&project=idc-converted-data&prefix=&forceOnObjectsSortingFiltering=false
