fix(napari): cycle glasbey colours via CyclicLabelColormap#42
Merged
Conversation
Passing the raw glasbey palette list to add_labels made napari map large label IDs past the end of the palette, so every cell rendered one flat colour (green). Wrap the palette in a CyclicLabelColormap so each label value cycles through a distinct colour. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Bug
Labels rendered as one flat colour (all green). Passing the raw
glasbey.create_palette(...)list toadd_labels(colormap=...)makes napari map large label IDs past the end of the palette.Fix
Build the glasbey palette, convert to RGBA, and wrap it in a
napari.utils.colormaps.CyclicLabelColormap— each label value now cycles through a distinct glasbey colour. (Restores the working mechanism from before the gallery-style refactor, but keeps the glasbey package.)🤖 Generated with Claude Code
