Custom segment colors

[p.musse...@gmail.com]

Is it possible to specify colors of a segment? I'm using precomputed://gs://neuroglancer-janelia-flyem-hemibrain/v1.0/segmentation as the source.

There is no UI for it, but you can set the "segmentColors" layer property to an object that maps segment IDs (as base-10 strings) to colors (any CSS color specification will work).

E.g.

      "segmentColors": {
        "885168486": "#ff0000",
        "1073428001": "#008000"
      },

For example:
