brain_pal return HEX colours for the different ggseg atlases.

brain_pal(
  name = NULL,
  n = "all",
  direction = 1,
  unname = FALSE,
  package = "ggseg"
)

`name`	String name of atlas
`n`	Number of colours to return (or "all" [default])
`direction`	Direction of HEX, -1 reverses order Neccessary if applying palette to other data than the brain atlas it comes from.
