Hello,

An example:

color c1 = #FFFFFF;
color c2 = #BEBEBE;
color c3 = #7F7F7F;
color c4 = #3F3F3F;
color c5 = #000000;

color [] grays = {c1, c2, c3, c4, c5};

int num = 0;

void setup() 
  {
  size(500, 500);
  }

void draw() 
  {
  //background(0);
  if (frameCount%60 == 0)
    {
    num = int(random(0, 5));
    println(num, hex(grays[num]));
  	}
  fill(grays[num]);
  //println(hex(grays[num]));
  circle(width/2, height/2, 300);
  }

:)
