Benchmark: rgb vs rgba vs hex canvas

HTML Preparation code:

<canvas id="canvasOne" width="400" height="400"></canvas>
<canvas id="canvasTwo" width="400" height="400"></canvas>
<canvas id="canvasThr" width="400" height="400"></canvas>

Script Preparation code:

var canvasOne = document.getElementById("canvasOne");
var ctxOne = canvasOne.getContext("2d");

var canvasTwo = document.getElementById("canvasTwo");
var ctxTwo = canvasTwo.getContext("2d");

var canvasThr = document.getElementById("canvasThr");
var ctxThr = canvasThr.getContext("2d");

Tests:

alpha
ctxOne.beginPath(); ctxOne.fillStyle = 'rgba(231, 76, 60, 0.1)'; ctxOne.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
ctxThr.beginPath(); ctxThr.fillStyle = '#f9cec9'; ctxThr.arc(200, 200, 100, 0, Math.PI * 2, true); ctxThr.fill();

Let's break down the provided benchmark and explain what's being tested, compared, and their pros and cons.

**Benchmark Overview**

The benchmark is designed to compare the performance of three different color models when drawing on a 2D canvas using JavaScript: `rgba`, `rgb`, and hexadecimal (`#`) color values. The test creates three canvases with the same dimensions and draws a circle on each canvas using the specified color model.

**Color Models**

1. **RGBA (Red, Green, Blue, Alpha)**: This is a color model that includes an alpha channel, which allows for transparency. In this benchmark, `rgba` is used to draw a semi-transparent red circle.
2. **RGB**: This is a color model that only includes the red, green, and blue channels, without any alpha channel. In this benchmark, `rgb` is used to draw a solid red circle.
3. **HEXadecimal (`#`) Color Values**: This is a shorthand way of representing colors using a six-digit code. The first two digits represent the red value, the middle two digits represent the green value, and the last two digits represent the blue value. In this benchmark, `#f9cec9` is used to draw a solid yellowish-brown circle.

**Comparison**

The test compares the performance of each color model when drawing on the canvas. The benchmark measures the number of executions per second (FPS) for each color model.

**Pros and Cons of Each Approach**

1. **RGBA**:
	* Pros: Supports transparency, which can be useful in certain graphics scenarios.
	* Cons: Requires an alpha channel, which can add complexity to the drawing process.
2. **RGB**:
	* Pros: Simple and straightforward, with no need for an alpha channel.
	* Cons: Does not support transparency, which may limit its use cases.
3. **HEXadecimal Color Values**:
	* Pros: Compact and convenient way of representing colors, especially when used with solid colors.
	* Cons: May not be as flexible as other color models, especially when it comes to transparency.

**Other Considerations**

The benchmark also takes into account the browser (Chrome 84) and device platform (Desktop) being tested. This is important because different browsers and devices may have varying performance characteristics due to hardware and software differences.

**Alternatives**

If you wanted to modify this benchmark, here are some alternative approaches:

1. **Use a different color model**: You could try using other color models like `hsv` (Hue, Saturation, Value) or `cmyk` (Cyan, Magenta, Yellow, Key).
2. **Increase the complexity of the drawing**: Instead of drawing a simple circle, you could draw more complex shapes or patterns.
3. **Add more canvases**: You could add more canvases to the test, each with a different color model, and compare their performance.

Keep in mind that modifying this benchmark may require significant changes to the script preparation code, HTML preparation code, and benchmark definition.
