Tests:

RGBa
ctxOne.clearRect(0, 0, 400, 400); ctxOne.beginPath(); ctxOne.fillStyle = 'rgba(231, 76, 60, 1)'; ctxOne.arc(200, 200, 100, 0, Math.PI * 2, true); ctxOne.fill();
RGB
ctxTwo.clearRect(0, 0, 400, 400); ctxTwo.beginPath(); ctxTwo.fillStyle = 'rgb(231, 76, 60)'; ctxTwo.arc(200, 200, 100, 0, Math.PI * 2, true); ctxTwo.fill();
Hex
ctxThree.clearRect(0, 0, 400, 400); ctxThree.beginPath(); ctxThree.fillStyle = '#e74c3c'; ctxThree.arc(200, 200, 100, 0, Math.PI * 2, true); ctxThree.fill();
HSL
ctxFour.clearRect(0, 0, 400, 400); ctxFour.beginPath(); ctxFour.fillStyle = 'hsl(5, 74%, 90%)'; ctxFour.arc(200, 200, 100, 0, Math.PI * 2, true); ctxFour.fill();
