LED Ternary Multiplication

I was thinking about this today.
I see that you modified your original post to confirm my off-dim-bright interpretation.
But nothing more.

Waiting for some kind soul to post the complete job?

Here's a "trinary" counter display --

// trinary01
// trinary display
// three places

byte eval;
byte e2;
byte e1;
byte e0;
const byte pin9s = 11;
const byte pin3s = 10;
const byte pin1s = 9;
byte triDigit [3] = {0,15,220};

void setup ()
{
  pinMode(pin1s, OUTPUT);
  pinMode(pin3s, OUTPUT);
  pinMode(pin9s, OUTPUT);
  digitalWrite(pin1s,HIGH);
  digitalWrite(pin3s,HIGH);
  digitalWrite(pin9s,HIGH);
  delay(1000);
}

void loop ()
{
  for(eval=0; eval < 27; eval++)
  {
    e2 = eval / 9;
    e1 = (eval % 9) / 3;
    e0 = (eval % 9) % 3;  
    analogWrite(pin9s,triDigit[e2]);
    analogWrite(pin3s,triDigit[e1]);
    analogWrite(pin1s,triDigit[e0]);
    delay(1000);
  }
}
