Setting limit of random colours

Processing Coding Questions

Another option is to choose a random point on a color spectrum using lerpColor() and passing it two colors and a random value between 0-1.

color from = color(204, 102, 0);
color to = color(0, 102, 153);
void setup() {
  frameRate(1);
}
void draw() {
  // random background in color range
  color randc = lerpColor(from, to, random(1));
  background (randc);
  // draw color bar
  for(int i=0; i<10; i++){
    fill(lerpColor(from, to, i/10.0));
    rect(0,0,10,10);
    translate(10,0);
  }
}
