LaTeX code for boxes used in smartdiagram package

Question

I want to draw boxes with same color code and font like those used in the smartdiagram package. Can someone help provide some hint in doing this. See the diagram.

This answer will show you how to find the information you ask for in the sources (for v0.3b, dated 2016/12/23, distributed with TL2018).

Firstly look at the style file which says (only relevant content for you):

\usesmartdiagramlibrary{core.definitions}
\usesmartdiagramlibrary{core.styles}
\usesmartdiagramlibrary{core.commands}

So you have to search the three library files. You will be able to spot the following relevant definitions. So starting with the colors:

\@namedef{color@1}{red!40}
\@namedef{color@2}{cyan!40}
\@namedef{color@3}{blue!40}
\@namedef{color@4}{green!40}
\@namedef{color@5}{orange!40}
\@namedef{color@6}{yellow!40}
\@namedef{color@7}{magenta!40}
\@namedef{color@8}{brown!40}
\@namedef{color@9}{violet!40}
\@namedef{color@10}{teal!40}

And this describes your diagram:

   \begin{tikzpicture}[every node/.style={align=center,let hypenation}]

   \foreach \smitem [count=\xi] in {#2}  {\global\let\maxsmitem\xi}

   \foreach \smitem [count=\xi] in {#2}{%
   \edef\col{\@nameuse{color@\xi}}
   \IfStrEq{\option}{horizontal}{% true-horizontal-flow diagram
     \path let \n1 = {int(0-\xi)}, \n2={0+\xi*\sm@core@modulexsep} in
         node[module,drop shadow] (module\xi) at +(\n2,0) {\smitem};
   }{% false-horizontal-flow diagram
     \path let \n1 = {int(0-\xi)}, \n2={0-\xi*\sm@core@moduleysep} in
         node[module,drop shadow] (module\xi) at +(0,\n2) {\smitem};
   }
   }%

   % arrows omitted
   \end{tikzpicture}

Hence you will see that you need

\tikzset{module/.style={%
      \pgfkeysvalueof{/smart diagram/module shape},
      thick,
      draw=\sm@core@bordercolor,
      top color=white,
      bottom color=\col,
      text=\sm@core@textcolor,
      text width=\sm@core@moduletextwidth,
      minimum width=\sm@core@modulewidth,
      minimum height=\sm@core@moduleheight,
      font=\sm@core@modulefontsize,
      \sm@core@borderdecoration
   },
   % arrows omitted
}
