How to change the color of bullet-points in default environments in beamer?

I am making a beamer presentation using

\usetheme{Aalborg}

and I want to create blocks for definitions, theorems, remarks, exercises, proofs, examples etc. It seems that the default example-environment inherits some features from the default theorem-environment.

I want to be able to make itemizations and enumerations within the example-block environment such that the bullet-points have the same color as the background color of the example-block header. Right now, the color of the bullet-points in the example-environment have the same color as the background color of the theorem-environment block heder. How can this be fixed?

\documentclass[mathserif,9pt,trans]{beamer}
\usetheme[shownavsym,right]{Aalborg}

Answers

If you use \setbeamertemplate{blocks}[rounded][shadow=true] after you made all the adjustments of colours etc. you simply overwrite them again with the default behaviour of blocks. So you should change the order.

Some other comments about your code:

  • You can find an explicit warning in your log file telling you not to use the mathserif document class option, but \usefonttheme[onlymath]{serif}. Don't ignore warnings!

  • first setting \setbeamertemplate{section in toc}{\inserttocsection} and then immediately overwriting it with \setbeamertemplate{section in toc}[sections numbered] makes no sense

  • with an up-to-date tex distribution the following package are no longer necessary: \usepackage{fixltx2e}, \usepackage{etex}, \usepackage[utf8]{inputenc}

  • The following package are already loaded by beamer \usepackage{xcolor}, \usepackage{graphicx}, \usepackage{etoolbox}

  • the following packages are not necessary, beamer has its own mechanism for these: \usepackage{caption}, \usepackage{multicol}

  • don't load the same package multiple times, especially not with different options. You load the caption package no less than 3 times!!!!

  • Don't use \usepackage{colortbl}, but add xcolor={table} as documentclass option
