\arguments{
\item{aes_type}{The type of aesthetic to which the scale is being applied.
One of "color", "colour", or "fill".}

\item{...}{Arguments passed on to either the \pkg{colorspace} scale
functions — one of \code{\link[colorspace:scale_color_discrete_sequential]{colorspace::scale_color_discrete_sequential()}},
\code{\link[colorspace:scale_color_continuous_sequential]{colorspace::scale_color_continuous_sequential()}},
\code{\link[colorspace:scale_fill_discrete_sequential]{colorspace::scale_fill_discrete_sequential()}}, or
\code{\link[colorspace:scale_fill_continuous_sequential]{colorspace::scale_fill_continuous_sequential()}} — or to
\link[ggplot2:continuous_scale]{ggplot2::continuous_scale} or \link[ggplot2:discrete_scale]{ggplot2::discrete_scale}.}

\item{color}{A color value, in hex, to override the default color. Otherwise,
the primary color of the resulting scale is chosen from the xaringanthemer
slide styles.}

\item{direction}{Direction of the discrete scale. Use values less than 0 to
reverse the direction, e.g. \code{direction = -1}.}

\item{inverse}{If \code{color} is not supplied and \code{inverse = TRUE}, a primary
color is chosen to work well with the inverse slide styles, namely the
value of \code{inverse_header_color}}

\item{begin}{Number in the range of \code{[0, 1]} indicating to which point in the color scale the smallest data value should be mapped.}

\item{end}{Number in the range of \code{[0, 1]} indicating to which point in the color scale the largest data value should be mapped.}

\description{
\strong{Lifecycle:} \href{https://www.tidyverse.org/lifecycle/#maturing}{Maturing}

Color and fill single-color scales for discrete and continuous values,
created using the primary accent color of the xaringanthemer styles.  See
\code{vignette("ggplot2-themes")} for more information and examples of
\pkg{xaringanthemer}'s \pkg{ggplot2}-related functions.
