Magenta is one of the standard ANSI terminal colors, so that is probably the color you are seeing in the `dnf` output as "purple".

Simplest example, using module:
raku -e 'use Terminal::ANSIColor; say color("magenta"), "this is in purple(magenta)", color("reset");'

Just the four purples, in raw ANSI codes:
raku -e 'say "\e\[{.[0]};{.[1]}m {.[0]};{.[1]} \e\[m " for (0,1) X (35,95);'

Full color grid:
raku -e '
my @fg = (31..37) X+ (0,60);
my @bg = (41..47) X+ (0,60);
say "    ", @bg.fmt("--%3d--", " "); 
for @fg -> $f {
  print $f.fmt("%3d:");
  for @bg -> $b {
    for 0,1 -> $a {
      my $z = "$a;$f;$b";
      print "\e\[{$z}m $a \e\[m ";
    }
  }
  say "";
}'
