Retrieve a Circadia Lab palette

Source: R/palettes.R
circadia_palette.Rd

Returns a named character vector of hex colour codes for the requested palette. Suitable for direct use in ggplot2::scale_fill_manual() or ggplot2::scale_colour_manual().

Usage

circadia_palette(palette = "main", n = NULL, reverse = FALSE)

Arguments

palette

Name of the palette. One of "main", "core", "diverging", "diverging_simple", "blues", "warm", "seq_blue", "seq_coral", "seq_amber", "seq_ochre". Defaults to "main".

n

Number of colours to return. If NULL (default) all colours in the palette are returned. If n is smaller than the palette length the first n colours are returned; if larger an error is thrown.

reverse

Logical. Reverse the order of the palette? Default FALSE.

Value

A named (or unnamed for gradient palettes) character vector of hex colour codes.

Details

Gradient palettes come in two families:

  • Complex (multi-hue): "diverging", "blues", "warm"

  • Simple (monochromatic / direct interpolation): "diverging_simple", "seq_blue", "seq_coral", "seq_amber", "seq_ochre"
