Yup, it is a problem.  Tonight on the Channel 7 news in Old Angeles, it
even came up.  It turns out the local Metro which, amongst other things
runs the metro trains, is preparing to build eight more lines and is
seriously worried about running out of color names.  The reporter mentioned
colorblindness as one of the concerns because she was concerned about
patrons who couldn't distinguish among red, pink, and orange.  I think they
are mainly thinking that only one line at present is not named for a color
they have to stick with colors for naming the lines.  (It's the line that
runs along Exposition Boulevard from approximately the Coliseum -- actually
about 7th & Figeroa -- to Santa Monica, which is a relic of the Olympics
the first time they were held in LA.)

What I think they are forgetting is that the rules to accommodate disabled
folks these days are way tougher than they were when the Blue, Purple, and
Red Lines were built 20 years ago or so.

I'm just personally hoping that they don't wind up like NYC or Boston.  I
find the trains in both cities confusing.  No issues with DC or Atlanta.
Just my thoughts.

I did try to download the 3.7 MB document that is the NASA report, but the
server couldn't be reached.  I'll try tomorrow.
