I am using beamer for writing my presentation. I was initially using latex+dvipdf, then with the help of other tex.exchange users I recognized that I cannot use transparency in this way. So now I am switching to pdflatex.
Because I use personalized colors and didn't want to use RGB names, I was using names from dvipsnames, but now I have to switch to svgnames, and the color names are of course different. I would like to use a variable that stores the color name, so that I can choose a color to be defined either in svgnames or in dvipsnames, depending if I am using pdflatex or not.
I tried this
\else color1=PineGreen \fi
but it doesn't work, what should I do?
