I can't see how you can do well what you want; others more experienced may well have a trick to do it. Maybe something along the lines of:

my $x = "variable_name"; my $value = "value"; eval "\$$x = $value"; warn $@ if $@; print $color1;

Which works, but not under use strict.

My suggestion would be to change your approach to use a hash. This would greatly simplify things.

my %config; # use database (DBI) to read key / values into hash # ... $config{color1} = "red"; print $config{color1};

Update: Just re-read your question. You want a way to provide access to the %config hash on each page. You could use a module to do this, exporting the %config hash.
