Not sure what happened but my color scale ‘broke’ without me changing any of the code… maybe due to a module update… Now I can’t get _any_ custom color scale to work nor any Plotly built-in scale, like ‘hot’. This is what was working for a long time, live now at [http://www.policekillings.info](http://www.policekillings.info).

scale\_colors=[ “rgb(255,255,255)”, “rgb(254,178,76)”, “rgb(252,78,42)”, “rgb(189,0,38)”, “rgb(189,0,38)”,  
“rgb(189,0,38)”,“rgb(189,0,38)”,“rgb(128,0,38)”, “rgb(128,0,38)”]  
…  
color\_continuous\_scale=scale\_colors,  
…

But now my map is not using my color scale and is instead falling back to the default Plotly blue, purple, orange, yellow scale. So, color\_continuous\_scale setting is entirely being ignored for some reason.

Any ideas appreciated!
