This bug also shows up not only when running nested screens on the same server but also in scenarios like the following:

Start screen on host 'a'.
From that screen session, use ssh to connect to host 'b'.
On host 'b', start yet another screen session.

Terminal output in a window in the screen session on host 'a' which uses bright/bold colors will show up as such.  Identical output in any window in the screen session on host 'b' however will use the corresponding dark/non-bold colors.

So whatever wrong it is that happens here, the ssh session (the one between connecting the two screen sessions) seem to be pretty transparent to it, that, is, the ssh session does no seem to affect the bug.

I submitted this anonymously, so if someone with the authorization wants to update "Submitted by", that would be great.

When using a screen session inside another screen session, the bold/light/bright colors 8-15 appear as the non-bold/dark colors 0-7.

In the first screen session, "tput setaf 12;echo hello" will print a bright blue "hello" to the terminal and "tput setaf 4;echo hello" will use dark blue.  In the nested screen session, there is no difference in the output from these two commands.

I'm using Screen 4.0.3-11 and Xterm 235 from Ubuntu, both compiled with 256-color support and the appropriate $TERM environment variable.  Colors 0-7 and 16-255 all work just fine.
