I am trying kinda to make this figure in tikz but I do not know how it works. I tried with 

\tcbox[sharp corners, boxsep=5mm, boxrule=.5mm]

But I can not fill both sides with color.

If you prefer tcolorbox:

\documentclass{article} 
\usepackage[most]{tcolorbox}

\begin{document}
\begin{tcolorbox}[
    sharp corners, boxsep=5mm, boxrule=.5mm,
    colback=brown, width=5cm, 
    halign upper=left, valign upper=top,
    halign lower=right, valign lower=bottom,
    enhanced, segmentation empty,
    underlay = {
        \begin{tcbclipinterior}
            \filldraw[fill=orange, draw=tcbcolframe, line width=.5mm] (frame.south west)--++(90:1cm) to [out=5, in=185] ([yshift=-1cm]frame.north east)|-cycle;
        \end{tcbclipinterior}
}]
    A
    \tcblower
    B
\end{tcolorbox}
\end{document}

  • I approved this one since it is closer to my original question. I do not know though how to change position of A and B or add more text to different position inside the box. – Geo Mar 19 '19 at 15:28

    @Geo tcolorbox allows to have two different paragraphs upper and lower. But these paragraphs are formatted as normal paragraphs, they won't adjust to upper or lower designs unless you use parshape. About adding more text in different positions, you could always use an overlay but this is another question and we need more information to be able to solve it. – Ignasi Mar 19 '19 at 15:37
  • I meant add more text in brown or orange section. Like add "Hello" on either section but on a different position say up right or bottom left. – Geo Mar 19 '19 at 16:07

    @Geo replace A or B for the text you want and play with {v|h}align {upper|lower} options. And take a look at tcolorbox documentation. – Ignasi Mar 19 '19 at 16:10

Welcome to TeX.SE. From the next time try adding a compilable MWE, so that it will attract more users to answer your question.

You can start with (borders):

\documentclass{standalone}
\usepackage{tikz}
\begin{document}
    \begin{tikzpicture}
    \filldraw [black] (3, 2) --(3,0)--(0,0) plot [smooth, tension=2] coordinates { (0,0) (1,1) (2, 1) (3, 2)};
    \filldraw [red] (3, 2) --(0,2)--(0,0) plot [smooth, tension=2] coordinates { (0,0) (1,1) (2, 1) (3, 2)};
    \draw[yellow,  thick] (0,0)--(0,2)--(3,2)--(3,0)--cycle;
    \end{tikzpicture}
\end{document}

to get:

and I leave the rest of customisation for you to do ;).

  • this has no borders and if I do

    \filldraw [fill = red, draw=black] (0,0) rectangle (5,5); Then the borders are different than tcbox where I have \tcbox[sharp corners, boxsep=5mm, boxrule=.5mm]

     – Geo Mar 19 '19 at 09:34
  • @Geo you can manually draw the borders around them :) see my updated answer ;) – Raaja_is_at_topanswers.xyz Mar 19 '19 at 09:35

    thanks, I also did \filldraw [fill = red, draw=black] [sharp corners,line width=.5mm, inner sep=5mm] (0,0) rectangle (5,5);

    What I do not understand is the coordinates, in order to change the shape { (0,0) (1,1) (2, 1) (3, 2)} Can you point me where can I read more about it?
