 ### Color Palettes ###
 There are a few built-in palettes:
   `greypurple`, `aquablues`, `reds`, `redblue`, `RdYlBu`, `grass`, `winter`, `greens`,  `autumn`, `hot`, `viridis`, `plasma`, `parula`, and `cool`.

 ## TODO ##
 - Eliminate dependency on von-grid. At this point so much of the hex logic has been rewritten we do not use much from that library any more.
-- Combine the two .js's into one file
-- Add options to tune material. Or change to check if a material= component is attached to the same entity, and then use that instead.
+- If AFrame adds support for vertexColors=THREE.VertexColoring to the material component, change to read material options from a `material` component
 - Support JSON files that contain X/Y/Value tuples, ie scattered instead of continuous data
