Hi,

I'm working on a program in which colors fade back and forth from blue to black, and then when a switch is triggered (i'm using key-pressed currently until i have the switch hooked up), the blues fade into reds.  i want the red to remain a bright red until the switch is released, when the color will then fade back to blue and then to black.  currently, i have managed to get my blues/blacks working properly, but when i have them fade to red, the reds go up and down from black instead of staying red.  can anyone help me with this dilemma?  my code is below:



int b;
int l;
int v;
int d;

void setup()
{
 size(500,500);            
 background(0,0,255);    
 frameRate(5);

 b=100;
 d=0;
 l=0;
 v=0;
 
}

void draw()
{
if(keyPressed==false)
 
 background(b,0,l);

  if (b>0)
    {
      d=d-10;
    }
 
  if (b<0)
    {
      d=0;
    }

  if (l<10)
    {
      v=v+1;
    }
 
  if (l>250)
    {
      v=v-1;
    }
 
   l=l+v;
   b=b+d;
 
if (keyPressed==true)
 {
   if(key=='r')
   {
    background(b,0,l);

    if (l>10)
     {
       v=v-10;
     }
   
    if (l<0)
     {
       v=0;
     }
 
    if (b<250)
     {
       d=d+20;
     }
   
    if (b>250)
     {
       d=d-20;
     }

b=b+d;
l=l+v;
 
  }
 }
 
 print(b + "\n");
 print(l+"\n");
}
