Electric Field: Change the color of the arrows depending on the force applied to them.

[xlikesasukee]

I would like the color of the Arrows to change depending on the value of F you get for them.
This could happen inside this function.

function drawElectricField() {
  for (let x = 0; x < 1200; x += 40) {
    for (let y = 0; y < 1200; y += 40) {
      let base = new Complex(x, y);
      let F = calculateElectricFieldVector(base).mul(1e15);

      //getColor(F) get corresponding color out of F value

      let absF = F.abs();
      F = F.mul(1/absF);
      drawArrow(base, new Complex(base.re + F.re, base.im + F.im),[35, 144, 145]);
    }
  }
}

The color variable is already a parameter of my drawArrow funciton.
