When comparing Chroma.js vs red, the Slant community recommends Chroma.js for most people. In the question“What are the best JavaScript libraries for color manipulation?” Chroma.js is ranked 2nd while red is ranked 3rd. The most important reason people chose Chroma.js is:
The scale API of Chroma is particularly robust and makes Chroma stand out in regards to creating color pallets and visualizations. With the scale API you define a custom scale to match your data set, and define stop points to create hard points when you want the color to change on a threshold. It also supports non linear scales like log, k-means, and quantiles.

Pros
Pro Powerful color scale API
The scale API of Chroma is particularly robust and makes Chroma stand out in regards to creating color pallets and visualizations.

It also supports non linear scales like log, k-means, and quantiles.
Pro LAB and Hue-Chroma-Lightness support creates nicer color scales
Chroma is unique in its support for more advanced color spaces like LAB and HCL which can create more natural looking color spaces than the standard RGB and HSL variant.
Pro Powerful color manipulation API
Color.js has one of the most complete sets of color manipulation methods, with methods for directly setting each value in all its supported color spaces of rgb
, hsl
, hsv
, hwb
, and cmyk
, so you can set the following directly:
alpha
, red
, green
, blue
, hue
, saturation (hsl)
, saturationv (hsv)
, lightness
, whiteness
, blackness
, cyan
, magenta
, yellow
, black
It also has many relative manipulation methods with:
blacken
, clearer
, darken
, desaturate
, greyscale
, lighten
, negate
, opaquer
, rotate
, saturate
, and whiten
.
Pro CMYK support for print analysis
Color.js has CMYK support which most other color libraries don't have. While not necessary for everyone, CMYK can come in handy if you are doing any kinds of color manipulations that need to take print into account.
Cons
Con Doesn't have many color manipulation methods
Chroma has a relatively limited set of color manipulation methods, containing: 'alpha', 'darken', 'brighten', 'saturate', 'desaturate', and 'luminance', but missing important methods like hue manipulation, whiteness, greyscale, and negation.
