Changelog

3.1.2

  • fixed a bug in Lch interpolation of hue-less colors

3.1.1

  • fix: allow deep-imports in vite projects

3.1.0

  • feat: parse 'transparent' as black with 0% opacity - resolves #280
  • make it easier to access colorbrewer palette names - resolves #314
  • docs: explain differences to official colorbrewer scales - resolves #316
  • fix: correct parsing of modern css colors with percentage alpha - resolves #297
  • fix: css output for hue-less colors in lch() and oklch() - resolves #357

3.0.0

  • 🎉 NEW: Add support for modern CSS color spaces. This means you can now export and parse CSS colors in lab(), lch(), oklab(), oklch() space.
  • 🎉 NEW: you can now control the standard white reference point for the CIE Lab and CIE Lch color spaces via setLabWhitePoint.
  • Breaking: color.css() will no longer return legacy CSS colors like rgb(255, 255, 0) but use modern CSS colors like rgb(255 255 0) instead.
  • fix: you can now use chroma.js both via the default export as well as named exports in ES6.
  • fix: switch to W3C implementation of OKLab color space

2.6.0

2.5.0

  • refactored code base to ES6 modules

2.4.0

  • add support for Oklab and Oklch color spaces

2.3.0

  • use binom of degree n in chroma.bezier

2.2.0

  • use Delta e2000 for chroma.deltaE #269

2.0.3

  • hsl2rgb will, like other x2rgb conversions now set the default alpha to 1

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

  • scale.colors() now returns the original colors instead of just min/max range

1.2.0

  • added chroma.average for averaging colors

1.1.0

  • refactored chroma.scale
  • changed behaviour of scale.domain
  • added scale.classes
  • added scale.padding

1.0.2

  • standardized alpha channel construction
  • chroma.bezier automatically returns chroma.scale

1.0.1

  • added simple color output to chroma.scale().colors()

1.0.0

  • numeric interpolation does what it should
  • refactored and modularized code base
  • changed argument order of Color::interpolate
