Thanks for the suggestion. It gets rid of the warning, but the red color it
produces is much brighter than the red color I get by using
\documentclass[red]{beamer}. I think beamer actually uses "BrickRed" of the
dvips list (http://en.wikibooks.org/wiki/LaTeX/Colors#Predefined_colors) for
titles and backgrounds (although not for "\alert{text}"), but I don't know
how to force \usecolorheme{structure} to use these named colours. I tried
inserting \usepackage[usenames,dvipsnames]{color} in the preamble, but then
I get an "Option clash for package color" warning. The following is a
minimum example (comment the first line and uncomment the two commented
lines for comparison of the color of the titlebar):
\documentclass[red,hyperref={pdfpagelabels=false}]{beamer}
%\documentclass[hyperref={pdfpagelabels=false}]{beamer} %% the option to
avoid the warning ``Option `pdfpagelabels’ is turned off(hyperref) because
\thepage is undefined.''
\usecolortheme{whale}
%\usecolortheme[named=red]{structure}
\usepackage{lmodern} %% avoid warning ``Size substitutions with
differences(Font) up to 1.0pt have occurred.''
