Relativity. Each color is perceived in relation to other colors. The top and bottom bars each contain the same component colors, but a different display order causes individual colors to appear differently.

  void setup() {
    size(200, 200);
    noStroke();
    a = color(165, 167, 20);
    b = color(77, 86, 59);
    c = color(42, 106, 105);
    d = color(165, 89, 20);
    e = color(146, 150, 127);
    noLoop();
  }
  
  void draw() {
    drawBand(a, b, c, d, e, 0, 4);
    drawBand(c, a, d, b, e, height/2, 4);
  }

    for(int i = 0; i < width; i += barWidth*num) {
      for(int j = 0; j < num; j++) {
        fill(colorOrder[j]);
        rect(i+j*barWidth, ypos, barWidth, height/2);
