In my program Strange Attractor Explorer, SAX,  I have a really messed up coloring method and would like help on creating a new method.  There just isn't enough information I can find on how to do this.

The coding is large and somewhat scattered so I will just highlight the coloring method.
First this was my plan,
The formula is looped for a designated amount of time via iterations, then a pixel plot is produced from the equation, if we find a strange attractor a vast amount of pixels are plotted and some are repeated.  I want to color these pixels according to how many times they have been pegged by the formula.

So I have a method that just makes the pixel more exposed by the color of your choice.

Now I want to give the user a chance to make more color choices based one a sort of color mapping.  Like what Chaoscope does but with the same idea of exposure to the more pegged pixels.

So how do I change my program to do this?
Here's the code for just the coloring method:

Variables:

1. //COLOR & ITERATION CONTROL
   
   float rAdjust = 2.0;//Change Color, white is maxiterations/1000
   float gAdjust = 3.5;//Keyboard input r-,R+,g-,G+,b-,B+
   float bAdjust = 5.0;//Adjust these first before cp and cr and cs.
   
              //Color will equal maxiterations 0-Maxiterations range
   int maxiterations = 50000;//Set by pressing f1-f8,  f8 is changeable by pressing f,F
   
   int[] exposure = new int[rWidth*rHeight];//records the hit times of each pixel point creates the brightness of that pixel in the coloring section
   
   int cp = 2;//EXPOSURE exposure = exposure + (cp*cr*1000)*rgbAdjust*cs 
   float cr = 2.0;
   float cs = 2.0;
   

Color is changed in setup:

1. colorMode(RGB, maxiterations);//controls brightness.  White will always be at the last iteration.  This only effects the pixels hit separately.  look at the coloring section.
   

Before each render this is called:

1.     exposure[i] = round(cp*cr*1000);
   

Color Method

1. void colorPixels()
   { 
     if(xint < rWidth && xint > 0)
     {
       if(yint < rHeight && yint > 0 )
       {
         if(n>start)//Most numbers below one hundred aren't a part of the strange attractor
         {
           exposure[yint*rWidth+xint]++;
          
           c = color(exposure[yint*rWidth+xint]*rAdjust*cs, exposure[yint*rWidth+xint]*gAdjust*cs, exposure[yint*rWidth+xint]*bAdjust*cs);
          
           tmpPixels[yint*rWidth+xint] = c;
         }
       }
     }
   }
   

Thanks for any help in advance!
