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. 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.
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.
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.
