RGB LED controlled by controller.

Hi! really appreciate your time trying to help me out. I have adjusted my code to use an array and can clearly see it was the better option. However, I still cannot seem to be able to dim the light. I'll post my code below.

#include <IRremote.h>

  const int RECV_PIN = 7;
  IRrecv irrecv(RECV_PIN);
  decode_results results;
  
  const int redPin = 11;
  const int greenPin = 10;
  const int bluePin = 6;

  static int rgbValues[] = {255, 255, 255};
  
void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  irrecv.enableIRIn();
  irrecv.blink13(true);
  pinMode(redPin, OUTPUT);
  pinMode(greenPin, OUTPUT);
  pinMode(bluePin, OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  if (irrecv.decode(&results)){

    switch(results.value){
      
      case 0xFF30CF: //Keypad button 1
      rgbValues[0] = 255;
      rgbValues[1] = 0;
      rgbValues[2] = 0;
      break;

      case 0xFF18E7: //Keypad button 2
      rgbValues[0] = 0;
      rgbValues[1] = 255;
      rgbValues[2] = 0;
      break;


      case 0xFF7A85: //Keypad button 3
      rgbValues[0] = 0;
      rgbValues[1] = 0;
      rgbValues[2] = 255;
      break;


      case 0xFF6897: //Keypad button 0
      rgbValues[0] = 0;
      rgbValues[1] = 0;
      rgbValues[2] = 0;
      break;

      case 0xFF10EF: //Keypad button 4
      rgbValues[0] = 255;
      rgbValues[1] = 255;
      rgbValues[2] = 255;
      break;

      case 0xFF02FD: //Keypad button play/pause
      Serial.print("Red value is "); Serial.println(rgbValues[0]);
      Serial.print("Green value is "); Serial.println(rgbValues[1]);
      Serial.print("Blue value is "); Serial.println(rgbValues[2]);
      break;
      

      case 0xFFE01F: //Keypad button down
      if(rgbValues[0] >= 10){
        rgbValues[0] = rgbValues[0] - 10;
        }
      else{
        rgbValues[0] = rgbValues[0] * 1;
        }
        
      if(rgbValues[1] >= 10){
        rgbValues[1] = rgbValues[1] - 10;
        }
      else{
        rgbValues[1] = rgbValues[1] * 1;
        }
        
      if(rgbValues[2] >= 10){
        rgbValues[2] = rgbValues[2] - 10;
        }
      else{
        rgbValues[2] = rgbValues[2] * 1;
        }
        
      Serial.print("Red value is "); Serial.println(rgbValues[0]);
      Serial.print("Green value is "); Serial.println(rgbValues[1]);
      Serial.print("Blue value is "); Serial.println(rgbValues[2]);
      break;
    }

     RGB_colour(rgbValues[0], rgbValues[1], rgbValues[2]);
     
    irrecv.resume();
  }
}

void RGB_colour(int redValue, int greenValue, int blueValue){
  analogWrite(redPin, redValue);
  analogWrite(greenPin, greenValue);
  analogWrite(bluePin, blueValue);
  }

I can confirm that when I switch through the different colours and print the values on screen they do change to the specified value. I can flick between them as much as I want. When i press 0 to change the RGB values to 0,0,0 and try to dim then the values stay at 0 as I wanted and I can flick back to another colour.

However, when I try to dim with a value above 10 then the specified amount is taken off the RGB value, it is printed to the screen but the actual RGB light does not change colour and I cannot change the colour back after pressing the dim button. I have to reset the board to be able to flip between the colours again.

Thanks again if anyone is able to help me out.
