# Die Hauptfarben des Corporate Designs der Universität Hamburg sind
# Rot (CMYK 0/100/100/0) und Blau (CMYK 87/49/0/0) – barrierefreier Blauton.
# Diese leiten sich zum einen vom Rot des Uni-Logos ab, zum anderen soll das Blau
# die Nähe der Stadt Hamburg und damit die Nähe zum Wasser symbolisieren.
# Das Blau transportiert ebenso Raum und Perspektive.
# Schwarz wird für den Fließtext verwendet.
# Als Alternative kann das Steingrau verwendet werden.
# Für Tabellen/Diagramme und Organigramme dürfen auch Abstufungen von
# Rot, Blau und Steingrau verwendet werden (siehe Seite 25).
#
# Wichtig:
# - Blau und Rot sollen subtil eingesetzt werden, nicht zu bunt:
# eher Designelemente wie Linien einfärben, keine ganzen Textpassagen.
# - Gewichtung der beiden Farben muss gleich sein

# Color palette(s):
# - uni_hamburg_1: Primary colors of Uni Hamburg ----
#' Primary colors of the University of Hamburg, Germany
#'
#' \code{uni_hamburg_1} provides the four primary colors
#' of the \href{https://www.uni-hamburg.de}{University of Hamburg}, Germany.
#'
#' The two main colors are \code{"rot"} (also defined as Pantone 485C or CMYK 0/100/100/0)
#' and \code{"blau"} (also defined as CMYK 87/49/0/0).
#' These colors should be weighted equally and in a subtle fashion
#' (i.e., as color accents, not large areas or entire texts).
#'
#' The auxiliary colors \code{"black"} and
#' \code{"steingrau"} (also defined as Pantone 432U or CMYK 45/11/11/73)
#' are used for text.
#'
#' Colors shades may be used in diagrams or visualizations.
#' See examples and the \code{\link{ac}} and \code{\link{usecol}} functions
#' for creating color gradients.
#'
#' @return
#' A named vector of colors (HEX/HTML codes of type character).
