Just noticed this as I copied the colorscales into another project... [`YIGnBu`](https://github.com/plotly/plotly.js/blob/master/src/components/colorscale/scales.js#L15) should really be `YlGnBu` and [`YIOrRd`](https://github.com/plotly/plotly.js/blob/master/src/components/colorscale/scales.js#L27) should really be `YlOrRd` Will require some backward compatibility shims if we fix this, unfortunately...
