How do you get random RGB in Javascript? [duplicate]

Question

I have this code that uses RGB color selection and I was wondering how to make JavaScript do a random color using the RGB method and remember it throughout the code.

EDIT: I tried this:

var RGBColor1 = (Math.round, Math.random, 255) var RGBColor2 = (Math.round, Math.random, 255) var RGBColor3 = (Math.round, Math.random, 255) 

but it doesn't work. Help please!

EDIT 2: The code uses this:

g.fillStyle="rgba(R,G,B,0.2)"; g.strokeStyle="rgba(R,G,B,0.3)"; E(); 

The letters represent the color of RGB.

EDIT 3: The doubles of this question are using HEX values, not RGB values.

Answer 1

function random_rgba() {     var o = Math.round, r = Math.random, s = 255;     return 'rgba(' + o(r()*s) + ',' + o(r()*s) + ',' + o(r()*s) + ',' + r().toFixed(1) + ')'; }  var color = random_rgba();  g.fillStyle   = color; g.strokeStyle = color; 

FIDDLE

Answer 2

const randomBetween = (min, max) => min + Math.floor(Math.random() * (max - min + 1)); const r = randomBetween(0, 255); const g = randomBetween(0, 255); const b = randomBetween(0, 255); const rgb = `rgb(${r},${g},${b})`; // Collect all to a css color string
