I have 8 common looking varibles and I need to check for them all in one line of a file to change the font color. But when I ran the following all it did was exactly what I told it to do. it replaced $red1 with $red1 when what I wanted it to do was replace $red1 with "black" and $red2 with "red". 
for ($i = 1; $i < 9; $i++) {
     $_ =~ s/\$red$i/\$red$i/sg;                                      
+     
     }
