Does this feature still work? When I type chroma.ColorScale, I get undefined

I think that is outdated. Have a look at https://github.com/gka/chroma.js/blob/master/doc/api.md#working-with-color-scales

OK, so I found this code in a project:

var hot = new chroma.ColorScale({
    colors: [ '#000000', '#0B16B5', '#FFF782', '#EB1250' ],
    positions: [ 0, 0.4, 0.68, 0.85 ],
    mode:'rgb',
    limits:[0, 300]
});

hot.getColor(value).hex();

How can I translate this to the new format?

I think your example would be:

var hot = chroma.scale(
                       ['#000000', '#0B16B5', '#FFF782', '#EB1250'],
                       [0, 0.4, 0.68, 0.85]
                      )
                       .mode('rgb')
                       .domain([0, 300])

hot(value).hex()

Does this do what you're expecting it to do?
