Powerdot,likes beamer, is a screen presentation tool for latex. I prefer Powerdot to Beamer,it is simple,and has discernible math texts and good support of pstricks. However, the Beamer text is certainly more sharp and "impressive" than Powerdot.So, the choice of them is trade-off.
Each of them has its build-in styles,but the style colors can be changed with writing some syntax,makes it more flexible ones. Here is the code for Powerdot:
\documentclass[paper=screen,
mode=present,clock,style=aggie,
display=slidesnotes]{powerdot}
\pddefinepalettes{my}{
\definecolor{pdcolor1}{rgb}{0,0,0}
\definecolor{pdcolor2}{HTML}{0033FF}
\definecolor{pdcolor3}{rgb}{.96,.94,.89}
\definecolor{pdcolor4}{rgb}{.89,.85,.69}
}
\pdsetup{
lf=Applied Microeconometrics,
rf=chang,
palette=my
}
the bold texts are main body to change the colors of style aggie.
pdcolor1-text color
pdcolor2-section text or line color
pdcolor3-background color
pdcolor4-bottom area colors
after set-up, we call this set-up by adding the syntax "palette=my" in pdsetup.
Of course, there are many latex packages support screen presentation.you may lik to this site for detail
