Hello, im making a small typewriter program and i wish to change the color of the individual characters.
So far i have this but it changes the color of everything i typed plus it doesn't n keep it.
Anyone can help or point me the resources i should look into? I want to press for example 1, and change to yellow, 2, other color and so on. But keeping the typing already done in the color chosen.. I have read as much as i can and i am stuck now :/
I am using a code i found for a terminal emulator to do this.. Any help appreciated, thanks!

1. PFont myFont;
   String[] myString;
   int numLines;
   int lineSpacing = 20;
   int counter;
   int cursorBlink = 15;
   int numColumns = 56;
   
   
   void setup(){
     size(640,480);
     frameRate(30);
     numLines = (int) (height/lineSpacing);
     smooth();
     myString = new String[numLines];
     for (int i=0; i<numLines; i++){
       myString[i] = "";
     }
     consolePrint(" start");
     counter = 0;
     myFont = loadFont("glyphs.vlw");
     textFont(myFont,20);
   
    
   }
   
   void draw(){
     background(0);
     fill(#14FA7D);
          if (keyPressed) {
       if (key == '1' || key == '1') {
         fill(#F3FC00);
       }
     } else {
       fill(#14FA7D);
     }
     for (int i=0; i<numLines-1; i++){
       text(myString[i],5,(i+1)*lineSpacing);
     }
     String addMe = "";
     if (counter++ > cursorBlink) addMe = "r";
     if (counter > 2*cursorBlink) counter = 0;
     text(myString[numLines-1]+addMe,5,numLines*lineSpacing);
   }
   
   //  input
   void processCommand(String s){
     if (s.length()>9 && s.substring(0,9).toLowerCase().equals("printfile")){
       printFile(s.substring(10));
     }
   
   }
   
   void consolePrint(String s){
     myString[numLines-1] = s;
     advanceLine();
    
   }
   
   void advanceLine(){
     for (int i=0; i<numLines-1; i++){
       myString[i] =myString[i+1];
     }
     myString[numLines-1] = " ";
   
   }
   
   void keyPressed(){
       
     if (key==ENTER||key==RETURN){
       advanceLine();
       String s = myString[numLines-2].substring(1);
       processCommand(s);
       return;
     }
