#' @param type (character) "message" (the default), "warning", "string", or "rmd". If "rmd" is used, the type of the RMarkdown document should be \code{html_document} the chunk option \code{results = "asis"} should be used.
#' @param direction (character) How should the colours be spread? One of
#' "horizontal" or "vertical".
#' @param recycle_chars (logical) Should the vector of colours supplied apply to the entire string or
#' should it apply to each individual character (if \code{direction} is vertical)
#' or line (if \code{direction} is horizontal), and be recycled?
#' @param add_leading_newline Should a newline be added at the beginning of the text? Useful for \code{cowsay} animals when \code{type = "rmd"}.
#' @param ... Further args.
