macrostcolorbox
I am new to the LaTeX. I want to customize tcolorbox for custom title with auto counter and background colour as per my choice say light red.
Also I want to change the font colour of title and inside text contents also as per my choice to say dark red/blue. How can I do this. Please help.
The basic MWE is as provided by feculededentier in the below link page
I have found this page Example numbers with respect to chapters in tcolorbox title
May I assist with a second answer? It removes the segmentation but keeps the 'beamerish' look also for boxes with title. For demonstration, I added a third box with a title and a shrinked space between upper and lower part which you may prefer.
My examples also contain a shadow which you can remove by adding the option no shadow.
\documentclass{beamer}
\usepackage{tcolorbox}
\tcbuselibrary{skins}
\makeatletter
\tcbset{beamer without segmentation/.style={%
beamer,segmentation code=,
interior titled code={{\tcb@spec{beamer@color}\tcb@drawwithtitle@path}\tcb@drawspec@T},
interior code={{\tcb@spec{beamer@color}\tcb@drawwithouttitle@path}}}}
\makeatother
\begin{document}
\begin{frame}
\tcbset{colframe=blue!40!black,colback=blue!20!white}
\begin{tcolorbox}[beamer without segmentation,width=2cm,nobeforeafter]
test
\tcblower
test
\end{tcolorbox}
%
\begin{tcolorbox}[beamer,width=2cm,nobeforeafter]
test
test
\end{tcolorbox}
%
\begin{tcolorbox}[beamer without segmentation,width=3cm,nobeforeafter,
title=My Title,middle=1pt]
test
\tcblower
test
\end{tcolorbox}
\end{frame}
\end{document}
I suggest the usage of \newtcbtheorem -- it is configurable with options like any other tcolorbox environment, the title content is used from the 2nd argument. The 3rd. argument is meant for the label and can be left empty if not needed.
By using auto counter each theorem defines a 'personal' counter, with number within=.. there's fine control on the numbering style.
The general syntax of a \newtcbtheorem definition is
\newtcbtheorem[init options]{theoremenvname}{Theorem Name}{options}{prefix}
where prefix is prepended to a possible label, i.e. if the prefix is def the label for foo would be def:foo, \newtcbtheorem uses a pre-defined label separator :, but this can be changed with the option label separator=...
The example for method environment shows how to specify the options.
Edit: tcolorbox theorem numbering is a related question.

Best Answer
To very first approximation I would just take the answer you refer to, remove the
chapterstuff and add the colors.EDIT: One way to deal with the color issue is to introduce new macros.
