Rgb blinkg with millis?

Yesss, after a little, I did the blink :stuck_out_tongue:

int redPin =11;
int greenPin=10;
int bluPin=9;
int buttonPin=2;
int buttonState=0;
unsigned long previousMillis=0;
unsigned long interval1= 1000;
unsigned long interval2= 3000;
unsigned long interval3= 5000;
unsigned long interval4= 7000;
unsigned long interval5= 9000;
unsigned long interval6= 11000;
unsigned long vuelta=12000;
long int fade_goTime;
int fade_break = 100;

void setColor (int red,int green,int blu)
{ 
 
  analogWrite(redPin, red);
  analogWrite(greenPin, green);
  analogWrite(bluPin, blu);  
}

void setup()
{
  pinMode(redPin, OUTPUT);
  pinMode(greenPin,OUTPUT);
  pinMode(bluPin,OUTPUT);
  pinMode(buttonPin,INPUT);
  fade_goTime = millis();
}

void loop()
{
  buttonState=digitalRead(buttonPin);
  if (buttonState ==0)
  {
    unsigned long currentMillis = millis();
    if (currentMillis - previousMillis == interval1) 
   { 
    setColor( 255, 0, 0); //red
   }
   if (currentMillis - previousMillis == interval2) 
   { 
    setColor( 0, 255, 0); //green
   }
    if (currentMillis - previousMillis == interval3) 
   { 
    setColor( 0, 0, 255); //blue
    }
    if (currentMillis - previousMillis == interval4) 
   { 
    setColor( 255, 255, 0); //yellow
    }
    if (currentMillis - previousMillis == interval5) 
   { 
    setColor( 0, 255, 255); //aqua
    }
    if (currentMillis - previousMillis == interval6) 
   { 
    setColor( 255, 0, 255); //purple
    
   }
    if (currentMillis-previousMillis==vuelta)
    {
      previousMillis=currentMillis;  
    }
  }
   else
  {
   ////////////////FADE
      if(  millis() >= fade_goTime) 
{
  static unsigned int rgbColour[3] = {255,0,0}; //Start on red
  static int incColour = 1;
  static int decColour = 0;
  static int i = -1;
     
      // cross-fade the two colours.
      i++;
      if(i > 255) {
        i=0;
        decColour ++;
        if(decColour >2) decColour = 0;     
        if (decColour == 2)  incColour = 0;
        else incColour = decColour +1;
      }

       
        rgbColour[decColour] -= 1;
        rgbColour[incColour] += 1;
       
        setColor(rgbColour[0], rgbColour[1], rgbColour[2]);     
       fade_goTime = millis() + fade_break;       
}
   
  }
}

The problem I'm facing now is with the fade, I just copied a fade code I found here and pasted it, did some tweaks and put it at work, the problem is when I push the button to change, it starts to fade but blinks once in a while :S What could be the problem now?

Thank you for the help :stuck_out_tongue:

Also, they may be another way to do the blinking code shorter and easier, but I can't think how.
