Select one or more colors from the Flexoki palette.

Usage

flex(col, sat = 400, code = "hex", palette = flexoki)

Arguments

col: Character string specifying one or more hues of colors (see Details).
sat: Number specifying the saturation level. If col = "paper" or col = "black" this defaults to sat = NA (see Details).
code: Character string specifying the form of color code (default = "hex").
palette: Name of the chosen color palette; flexoki is the only option at this time.

Value

For code = "hex", a scalar (or vector) of one (or more) hexadecimal color code(s).

For code = "rgb", a tibble with columns c("red", "green", "blue")

Details

There are three different options for monochromatic base hues: off-white (col = "paper"), black (col = "black"), and a 12-level gray-scale (col = "gray" or col = "base").

There are several options for accent colors, each specified using the col argument and offered in 12 increasing levels of saturation. The color options are:

c("red", "orange", "yellow", "green", "cyan", "blue", "purple", "magenta")

The level of saturation is denoted by an integer from the following set, ordered from lightest to darkest:

c(50, 100, 150, 200, 300, 400, 500, 600, 700, 800, 850, 900, 950).

The function will work with vector arguments for col and sat. If the vectors are the same length, the function assumes a 1:1 correspondence between a specified color and the saturation, such that col = c("red", "blue") and sat = c(100, 200) would yield the hexadecimal equivalent of "red-100" (#FFCABB) and "blue-200" (#92BFDB). If one of the arguments is a vector and the other is a scalar, the shorter argument is recycled (see examples).

Examples

## two different colors with same saturation levels
#> flex(c("blue", "red"), 100)

## two different colors with same saturation levels in RGB
flex(c("blue", "red"), 100, code = "rgb")
#> # A tibble: 2 × 3
#>     red green  blue
#>   <int> <int> <int>
#> 1   198   221   232
#> 2   255   202   187

## gray with different saturation levels
flex("gray", c(100, 200))
#> [1] "#E6E4D9" "#CECDC3"

## three colors with specific saturation levels
flex(c("blue", "red", "green"), c(100, 200, 300))
#> [1] "#C6DDE8" "#F89A8A" "#A0AF54"
