Your attachments to the original query did not make it through to 
anywhere I could see them, so I do not know what colors you are talking about.
The new color scheme was not made a default until version 5, so whatever
you are seeing in version 4.6 must be something else.

Version 4.6 does however support the mechanism for setting linecolors
that was eventually used in version 5 to change the default.
It is possible that your initialization file is using this mechanism
to change colors on entry.  If that is what is happening you can either
edit the initialization file or bypass it using the "-d" flag.
     gnuplot -d

Otherwise, more information needed.
Is this affecting all terminal types or only a particular terminal?
Is there some reason you would upgrade from version 4.0 only as far
as 4.6 rather than 5.2 (current)?
