% Base colors
% ===========
%
% The metropolis color theme is defined in terms of four main styles:
%
% - normal text  (dark fg, light bg)
% - alerted text (colored fg, should be visible against dark or light)
% - structure    (light fg, dark bg)
% - block title  (dark fg, light-ish bg)
%
% An easy way to customize the theme is to redefine these colors using
%
%     \setbeamercolor{ ... }{ fg= ... , bg= ... }
%
% in your preamble.
%

\setbeamercolor{normal text}{%
  fg=mDarkTeal,
  bg=black!2
}

\setbeamercolor{alerted text}{%
  fg=mLightBrown
}

\setbeamercolor{structure}{%
  fg=white,
  bg=mDarkTeal
}

\if@beamer@metropolis@blockbg
  \setbeamercolor{block title}{%
    use=normal text,
    fg=normal text.fg,
    bg=normal text.bg!80!fg
  }
\else
  \setbeamercolor{block title}{use=normal text, parent=normal text}
\fi
