I'm working on a beamer theme. I know I can set colors for an element with

\setbeamercolor{element name}{fg=colorname}

Now there are a lot of possible elements, but I only need very few colors in my theme. So it would be nice to be able to overide all colors first with my default color an then only specify the few exceptions to my default color. Is this possible?

Most of the beamer element colors in a beamer template are dependent on other colors. Look for example at the default color theme. Nearly all the element's colors are dependent on these four "base colors".

\setbeamercolor{normal text}{fg=black,bg=white}
\setbeamercolor{alerted text}{fg=red}
\setbeamercolor{example text}{fg=green!50!black}
\setbeamercolor{structure}{fg=beamer@blendedblue}

Also there are the four palette colors (again here the definition in the default color theme), which are kind of important.

\setbeamercolor{palette primary}{use=structure,fg=structure.fg}
\setbeamercolor{palette secondary}{use=structure,fg=structure.fg!75!black}
\setbeamercolor{palette tertiary}{use=structure,fg=structure.fg!50!black}
\setbeamercolor{palette quaternary}{fg=black}

So if you design your own color theme you should keep that in mind. Using these "base colors" make it much easier and faster to define your own color theme.

In short: if you use the default color theme, changing the beamer color structure should already change a lot.
