I'm trying to use this KML (converted with toGeoJSON) as a Data-driven Line. The dataset contains a hex color value for each stroke (ex. #7ee500). There are 100+ different color values, to give resolution to speed evolution. The data-driven lines seem to max out at 7 stops. Is there a way to simply match the Mapbox stroke value to the hex color value already available in the dataset?

Imported the dataset and tried to play with Style settings under Components > Data-driven Lines. Also played with Layers > Heatmap, no avail.
