You could use print instead of system and echo: 

print "\e[36;38mWELCOME\e[37m TO PERLMONKS\n";

And - if you need it more than once - you might want to put the respective ANSI escape sequences in variables, so it's easier to type and read: 

my $UL = "\e[36;38m";
my $UE = "\e[37m";

print "${UL}WELCOME$UE TO PERLMONKS\n";
