Description
For the [GeoJSON custom styling](http://cesiumjs.org/Cesium/Apps/Sandcastle/index.html?src=GeoJSON%20and%20TopoJSON.html&label=DataSources) sandcastle demo, the polygons are bright and happy in 3D:

But are much darker in 2D and CV:

I wouldn't expect there to be such a big difference
Contributor guide
Research direction
Start by opening the linked GeoJSON custom styling Sandcastle demo and reproducing the polygon appearance in 3D, 2D, and Columbus View (CV). Compare the rendering behavior across those modes and identify why the 2D/CV polygons are darker. Done means the lighting or appearance is consistent across modes, with regression coverage if the existing test structure supports it.
