This seems to be an issue with version 0.40 of Data::Printer which is the current version on metacpan. If I install version 0.99 from GitHub I get colors with Perl 6 also. See also this issue.

I debugged version 0.40 a little bit, and it seems like the only difference between the call to p @a from Perl 5 version versus the same call from Perl 6, is that the Perl 6 call is called in list context, so wantarray returns true for the Perl 6 call, this apparantly makes Data::Printer turn off coloring somehow.
