Script Preparation code:

var canvasOne = document.getElementById("canvasOne");
var ctxOne = canvasOne.getContext("2d");

var canvasTwo = document.getElementById("canvasTwo");
var ctxTwo = canvasTwo.getContext("2d");

var canvasThree = document.getElementById("canvasThree");
var ctxThree = canvasThree.getContext("2d");

var canvasFour = document.getElementById("canvasFour");
var ctxFour = canvasFour.getContext("2d");

Tests:

RGBa
ctxTwo.fillStyle = 'rgba(255, 255, 255, 0.3)'; ctxTwo.fillRect(0, 0, 400, 400); ctxOne.beginPath(); ctxOne.fillStyle = 'rgba(231, 76, 60, 0.1)'; ctxOne.arc(200, 200, 100, 0, Math.PI * 2, true); ctxOne.fill();
RGB
ctxTwo.fillStyle = 'rgba(255, 255, 255, 0.3)'; ctxTwo.fillRect(0, 0, 400, 400); ctxTwo.beginPath(); ctxTwo.fillStyle = 'rgb(249, 206, 201)'; ctxTwo.arc(200, 200, 100, 0, Math.PI * 2, true); ctxTwo.fill();
Hex
ctxThree.fillStyle = 'rgba(255, 255, 255, 0.3)'; ctxThree.fillRect(0, 0, 400, 400); ctxThree.beginPath(); ctxThree.fillStyle = '#f9cec9'; ctxThree.arc(200, 200, 100, 0, Math.PI * 2, true); ctxThree.fill();
HSL
ctxThree.fillStyle = 'rgba(255, 255, 255, 0.3)'; ctxThree.fillRect(0, 0, 400, 400); ctxThree.beginPath(); ctxThree.fillStyle = 'hsl(15, 90%, 64%)'; ctxThree.arc(200, 200, 100, 0, Math.PI * 2, true); ctxThree.fill();
