According to lmarini, the sensors had 'color' information. But I am not seeing it in: https://seagrant-dev.ncsa.illinois.edu/clowder/api/geostreams/sensors

I looked at what seagrant-dev has. And it seems like the coloring for each sensor would depend on the properties.type.id and you compare it with the following source/color mapping:

getColor : function(source)

{ return source == "epa" ? "#0D71BA" : source == "usgs" ? "#39B54A" : source == "lec" ? "#4D6363" : source == "gsfmp" ? "#CC2128" : source == "iadn" ? "#F7941E" : "white"; }

,

Source is what is on properties.type.id

The colors come from seagrant/sources.js (gltg/sources.js and imlczo.js)
