var ctxThr = canvasThr.getContext("2d");

Tests:

alpha
ctxOne.beginPath(); ctxOne.fillStyle = 'rgba(231, 76, 60, 0.1)'; ctxTwo.arc(200, 200, 100, 0, Math.PI * 2, true); ctxOne.fill();
no alpha
ctxTwo.beginPath(); ctxTwo.fillStyle = 'rgb(249, 206, 201)'; ctxTwo.arc(200, 200, 100, 0, Math.PI * 2, true); ctxTwo.fill();
hex
ctxTwo.beginPath(); ctxTwo.fillStyle = '#f9cec9'; ctxTwo.arc(200, 200, 100, 0, Math.PI * 2, true); ctxTwo.fill();
