No, I think the more probable cause is how the colors are configured
in each terminal emulator, in this case 'screen'.

The translation of a given TTY color to X RGB values are entirely
controlled by how the terminal emulator is configured, hopefully this
is customizable in some way and not hard-coded in the emulator's code.
I suggest to dig into the docs of each emulator and perhaps search the
net for pertinent keywords.  Or maybe asking on some relevant forum.
