Sequential schemes¶

Sequential color schemes are available as continuous interpolators (often used with d3.scale_sequential) and as discrete schemes (often used with d3.scale_ordinal).

Each discrete scheme, such as d3.SCHEME_BLUES, is represented as an array of arrays of hexadecimal color strings. The \(k\)-th element of this array contains the color scheme of size \(k\); for example, d3.SCHEME_BRBG[9] contains an array of nine strings representing the nine colors of the brown-blue-green diverging color scheme. Diverging color schemes support a size \(k\) ranging from 3 to 11.

To create a diverging continuous color scale using the blues color scheme:

color = d3.scale_sequential(d3.interpolate_blues)

To create a diverging discrete nine-color scale using the PiYG color scheme:

color = d3.scale_ordinal(d3.SCHEME_BLUES[9])
