x_colorLookup

The goal is to provide a way that colors can be associated with the nominal data in the stream. A map is provided from regular expression to web color (color name or #RRGGBB). 

"x_colorLookup": {
    "Fair":"SkyBlue",
    "(?i).*cloud.*":"LightSteelBlue",
    "(?i)overcast":"LigthGrey",
    "(?i).*rain.*":"Green",
    "(?i).*storm.*":"DarkGreen"
}
