How to fully disable AWB on OV7670 Arduino Uno

I am turning off the AWB enable bit on register 0x13. I have also tried turning off the AEC/AGC bits in combination with the AWB bit. Have set {register 0x01 to 0x96} and {register 0x02 to 0x40} as well in trying to get a combination that turns off the white balancing. The outcomes are either incorrect RGB565 values, or AWB persisting. The values start out correctly, but over the next 5-10 seconds they move to a more "grayish" set of values when pointing camera at bright red color. I would expect Red close to 30, green around 10, and blue near 0. Here is sample data:

|RED | GREEN | BLUE |
| 28 | 6 | 0 |
| 15 | 4 | 0 |
| 11 | 4 | 0 |
| 7 | 3 | 0 |
| 7 | 3 | 0 |
| 7 | 3 | 0 |

It pretty much stays at these values.

   //Turn off white balance bit
    uint8_t AWBRegister = camera.readRegister(0x13);
    AWBRegister = AWBRegister - 0x02;

    if(camera.setRegister(0x13, AWBRegister) == false)
    {
      debugLEDBlink(6); //used for debugging
      for(int i; i < 5; i++)
      {
        delay(1000);
        if(camera.setRegister(0x13, AWBRegister) == true)
        {
          break;          
        }        
        debugLEDBlink(6); //used for debugging
      }
    }
