Specific question: In the LaTeX beamer \definecolor command, what color spaces can be specified? I have looked through dozens of examples and have found two types: either "\definecolor{rgb}<rgb-triplet>", or "\definecolor{gray}<graylevel>". Is it possible to use, for example "\definecolor{hsv}", "\definecolor{hsb}", "\definecolor{hsi}", "\definecolor{cyik}" ?
General question: Where can I find the complete specification for the beamer class? A web search reveals many links to "examples for beamer presentations", and the like. Some of these are excellent, but I would like to find the definitive specification.
thanks for your help !

Since beamer relies on xcolor, read the respective manual.Curious George wrote:[…] In the LaTeX beamer \definecolor command, what color spaces can be specified?

Read the beamer user guide. And since it also relies on pgf, read this manual, too.Curious George wrote:[…] Where can I find the complete specification for the beamer class?

Hi George,
welcome to the board!
You can easily access the documentation by typing
at the command prompt, the same for xcolor and pgf. Or use texdoc.net which has an interface for providing it online, just type the package or an alias into the search field there.
You can even access the documentation here via the forum, we have a syntax and a "doc" button for that. Just click one of the links:

Re: beamer | Color Definition
Thanks, Stefan and localghost for the welcome, and for the pointers to documentation. "texdoc xcolor" gave me the answers I needed. If anyone
else finds this thread, the answer to my specific question is yes, \definecolor supports several color systems besides rgb, including hsb and cmyk.
