IIRC .. you first need to have a version of screen that supports 256
colors _and_ specify --enable-colors256 when you ./configure it prior
to compile.

AFAIK 256-color support is not the default.  

If you didn't compile screen yourself -- if you are running a binary
distribution such as debian stable for instance .. it probably was not
enabled by the package maintainer.

Not sure if there's a way you can check on the configure options from
the binary.

Another thing is that you are going to need to have screen point to a
terminfo entry that supports 256 colors.  

I do the latter with the following .screenrc statement:

  term    "screen-256color-bce"     

Even if this turns out not to be necessary (?) to run your 256-color
test from a shell successfully, you will need a correct terminfo entry
for screen-mode apps that use it to determine the capabilities of the
underlying terminal anyway (mutt, vim, eg.)

I can't look into the details of my setup right now but I think the
above is all there is to it.
