Colour palette interpolated between user-supplied colours

Linearly interpolates n colours through the sequence of color, via grDevices::colorRampPalette(). Unlike palette_manual() (which interpolates a single curated 5-colour palette), color here is supplied directly by the caller – any number of colours, in any order.

Usage

palette_gradient(color, n, space = c("Lab", "rgb"))

Arguments

color

A character vector of at least two colours to interpolate through, in order.

n

A single positive whole number: the number of colours to return.

space

The colour space interpolation happens in, forwarded to grDevices::colorRampPalette()'s own space argument: "Lab" (the default) blends perceptually more evenly than "rgb", particularly for color pairs far apart in hue.

Value

A character vector of n hex colour strings.
