#' Extracts the dittoSeq default colors
#' @author Daniel Bunis
#' @param reps Integer which sets how many times the original set of colors should be repeated
#' @param get.names Logical, whether only the names of the default dittoSeq color panel should be returned instead
#' @return A string vector with length = 24.
#' @description Creates a string vector of 40 unique colors, in hexadecimal form, repeated 100 times.
#' Or, if \code{get.names} is set to \code{TRUE}, outputs the names of the colors which can be helpful as reference when adjusting how colors get used.
#'
#' These colors are a modification of the protanope and deuteranope friendly colors from Wong, B. Nature Methods, 2011.
#'
#' Truly, only the first 1-7 are maximally (red-green) color-blindness friendly, but the lightened and darkened versions (plus grey) in slots 8-40 still work releatively well at extending their utility further.
#' Note that past 40, the colors simply repeat in order to most easily allow dittoSeq visualizations to handle situations requiring even more colors.
#'
#' The colors are:
#'
#' 1-7 = Suggested color panel from Wong, B. Nature Methods, 2011, minus black
#' \itemize{
#' \item 1- orange = "#E69F00"
#' \item 2- skyBlue = "#56B4E9"
#' \item 3- bluishGreen = "#009E73"
#' \item 4- yellow = "#F0E442"
#' \item 5- blue = "#0072B2"
#' \item 6- vermillion = "#D55E00"
#' \item 7- reddishPurple = "#CC79A7"
#' }
#'
#' 8 = gray40
#'
#' 9-16 = 25\% darker versions of colors 1-8
#'
#' 17-24 = 25\% lighter versions of colors 1-8
#'
#' 25-32 = 40\% lighter versions of colors 1-8

#' 33-40 = 40\% darker versions of colors 1-8
