[dependabot-preview]

Updates the requirements on chroma-js to permit the latest version.

Changelog

Sourced from chroma-js's changelog.

Changelog

2.0.2

• use a more mangle-safe check for Color class constructor to fix issues with uglifyjs and terser

2.0.1

• added chroma.valid() for checking if a color can be parsed by chroma.js

2.0.0

• chroma.js has been ported from CoffeeScript to ES6! This means you can now import parts of chroma in your projects!
• changed HCG input space from [0..360,0..100,0..100] to [0..360,0..1,0..1] (to be in line with HSL)
• added new object unpacking (e.g. hsl2rgb({h,s,l}))
• changed default interpolation to lrgb in mix/interpolate and average.
• if colors can't be parsed correctly, chroma will now throw Errors instead of silently failing with console.errors

1.4.1

• chroma.scale() now interprets null as NaN and returns the fallback color. Before it had interpreted null as 0
• added scale.nodata() to allow customizing the previously hard-coded fallback (aka "no data") color #cccccc

1.4.0

• color.hex() now automatically sets the mode to 'rgba' if the colors alpha channel is < 1. so chroma('rgba(255,0,0,.5)').hex() will now return "#ff000080" instead of "#ff0000". if this is not what you want, you must explicitly set the mode to rgb using .hex("rgb").
• bugfix in chroma.average in LRGB mode (#187)
• chroma.scale now also works with just one color (#180)

1.3.5

• added LRGB interpolation

1.3.4

• passing null as mode in scale.colors will return chroma objects

1.3.3

• added color.clipped
• added chroma.distance
• added chroma.deltaE
• color.set now returns a new chroma instance
• chroma.scale now allows disabling of internal cache
• chroma.average now works with any color mode
• added unit tests for color conversions
• use hex colors as default string representation
• RGB channels are now stored as floats internally for higher precision
• bugfix with cubehelix and constant lightness
• bugfix in chroma.limits quantiles
• bugfix when running scale.colors(1)
• bugfix in hsi2rgb color conversion

1.2.2
