Distinct, colorblind-friendly line palette across families

Uses one high-contrast tone (default A700) from different families to maximize separation between lines. This departs from the single-family aesthetic but improves readability for multi-series lines.

Usage

scale_color_albers_distinct(n = NULL, tone = c("A700", "A900", "A500"), ...)

Arguments

n

Number of colors needed; defaults to length of available families (6).

tone

One of "A700", "A900", or "A500".

...

Passed to ggplot2::scale_color_manual().

Value

A ggplot2 scale object.

Examples

# \donttest{
if (requireNamespace("ggplot2", quietly = TRUE)) {
  df <- data.frame(x = 1:6, y = 1:6, g = paste0("G", 1:6))
  ggplot2::ggplot(df, ggplot2::aes(x, y, color = g)) +
    ggplot2::geom_point() + scale_color_albers_distinct()
}
