RGB Halo Project

Hi all,

I have a tiny LED that is soldered onto a breadboard. The three colours go to to these pins.
redPin = 11;
greenPin = 10;
bluePin = 9;

In my situation the values that you would use for an analogWrite need to be inverted. Meaning that if i want the red colour to be 255, it would need to output 0 to be on full (LOW = ON , HIGH = OFF) i cannot change this as this is meant for the project i am doing.

I want to be able to run the RGB values at 120Hz for 8ms (8000microseconds)
The formula to do this is the following:
(Value/255) * 8000

Here is a quick scenario:

(Serial Monitor)
Red Value ( 0-255 ): 255
Green Value (0-255): 190
Blue Value(0-255): 0

(Code)
(Because of the wiring these values would need to be inverted)

tRed = 255 - Red Value
tGreen = 255 - Green Value
tBlue = 255 - Blue Value

tRed = 0 (Fully On)
tGreen = 65 (Partially on)
tBlue = 255 (Completly Off)

The Code will the need to work out its delay to be turned on by doing the formula
formulaR = (tRed/255.0)*8000;
formulaG = (tGreen/255.0)*8000;
formulaB = (tBlue/255.0)*8000;

formulaR = 0
formulaG = 2039
formulaB = 8000;

Now this is the part that i am stuck at in the code. I need the red to be at LOW for the whole 8000 microseconds. the green to be on for 2039 microseconds. but then i need Blue to be off for 8000 microseconds because the input was originally 0 meaning that there should be no Blue at all.

I dont know if i have explained this properly. If you need any more information just comment:)

I need to be writing this in digitalWrite form aswell.

This is what i have so far

int redPin = 11;
int greenPin = 10;
int bluePin = 9;

String msg1 = "Enter Red Value (0-255): ";
String msg2 = "Enter Green Value (0-255): ";
String msg3 = "Enter Blue Value(0-255): ";

int tR,tRa;
int tG,tGa;
int tB,tBa;

int formulaR;
int formulaG;
int formulaB;

void setup() 
{
  Serial.begin(9600);
  pinMode(redPin,OUTPUT);
  pinMode(greenPin,OUTPUT);
  pinMode(bluePin,OUTPUT);
  
  digitalWrite(redPin,HIGH);
  digitalWrite(greenPin,HIGH);
  digitalWrite(bluePin,HIGH);
}

void loop() 
{
  Serial.print(msg1);
  while(Serial.available()==0)
  {
    
  }
  tR = Serial.parseInt();
  Serial.println(tR);

  Serial.print(msg2);
  while(Serial.available()==0)
  {
    
  }
  tG = Serial.parseInt();
  Serial.println(tG);

  Serial.print(msg3);
  while(Serial.available()==0)
  {
    
  }
  tB = Serial.parseInt();
  Serial.println(tB);

  tRa = 255 - tR;
  tGa = 255 - tG;
  tBa = 255 - tB;

  formulaR = (tRa/255.0)*8000;
  formulaG = (tGa/255.0)*8000;
  formulaB = (tBa/255.0)*8000;

}
