I am trying to reproduce

![Screenshot from 2020-09-13 11-55-55.png](/image?hash=80a4827f3d52c52a95250e4916d53078a58e5a09a280e9110bf706439d9ea141)

but with my own colors.

To make the circles I started with:


\documentclass[xcolor={rgb}]{beamer}
\setbeamersize{text margin left=10mm,text margin right=5mm}
\setbeamertemplate{frametitle}[default][center]
\usepackage{tikz}
\newcommand{\tikzcircle}[3][red]{\tikz[baseline=-0.5ex]{\node[draw={#1}, fill={#1}, circle,text width=#2,minimum width=1.4em,text=black,align=center] at (0,0) {#3};}\hspace{0pt}}%
\definecolorseries{foo}{hsb}{step}{red!90!black}{\pgfmathresult,0,0}
\resetcolorseries[4]{foo}%
\begin{document}
\begin{frame}
\def\numdots{8}
\def\cols{1,2,3,4,1,2,3,4}
\foreach \x in {1,...,\numdots}{%
\tikzcircle[{foo!![\cols[\x]]}]{8pt}%
}%
\end{frame}
\end{document}


But this is wrong.

1. I need to be able to choose the colors of each circle.

2. Ideally I would have an outline for the circles as the example screenshot.

This is merely to honorably mention the amazing circledsteps package, which is written by an [amazing squirrel](https://topanswers.xyz/user?id=809&community=tex). :smile_cat: It seems to me that you have reached the point at which you might want to use the circles inside nodes of a tikzpicture. However, this prevents you from using a tikzpicture for creating these circles as this would mean that you nest tikzpictures (unless you want to use \saveboxes or play Russian roulette). On the other hand, with the circles created by circlesteps there is no problem. (I also think that these circles compile a tiny bit faster, but this is almost impossible to measure.) Then you can use the matrix library to create the tables, and to relatively align them to each other.

There are various things that one can change/improve, such as the programmatic coloring of the tables. (I am aware of the fact that there are users who find this too hacky, which is why there is also the above code.)

You can iterate over your list rather than counting from 0 to \numdots

Some notes about the non-working code:

- to get the numbers into your \tickcircle macro, a previous question changed the number of argument to one optional argument and two mandatory arguments - \tikzcircle[]{} is missing the second mandatory argument

- \cols[\x] is not what you think it is: 1,2,3,4,1,2,3,4[\x]. You can't just invent syntax and then expect it to work

- the definition of the colour series uses \pgfmathresult. If you simply delete the \pgfmathparse{} in the line before, you mustn't be surprised if the result is nonsense
