Works too:

my @rgb = map {hex($_) } unpack 'xa2a2a2', "#FF00FF"; print "(",join(',',@rgb),")\n";

    While we're busy doing silly pack/unpack strings:
    $str = '#FE00FD'; $str =~ tr/0-9a-fA-F//cd; # remove non-hex characters my @rgb = unpack 'C*', pack 'H*', $str; # pack hex as 3 bytes, unpack + into list of 3 character codes $" = ","; $\ = "\n"; print "(@rgb)";
    Result:
    (254,0,253)
