Color plays a crucial role in evoking emotions, setting the ambiance, and making your site’s overall design more cohesive.

We’ll go over everything you need to know about HTML codes in this post, so you can change and update your site find color names, etc. Learn how to choose a color scheme that consistently reflects your brand’s style, whether you’re redesigning a website or choosing a color palette for the first time.

HTML Color Codes

Red and yellow are two colors we see every day, and we know what they are called. There are hundreds of shades within each of these colors as well. In addition to pink, there are neon pinks, bubblegum pinks, roses, fuchsias, magentas, and countless others.

Even though we are trying to be more specific, different people can interpret these names differently. Neo pink can be fuchsia to one person and magenta to another.

Online HTML codes are used to eliminate this imprecision. These codes are interpreted by computers and displayed according to their meaning. Various formats are available, including Hex codes. We will examine this format in more detail below.

Hex Color Codes

Websites and other software applications use HTML codes the most. A hex code is composed of three bytes of hexadecimal numbers followed by a hashtag.

A pair of hexadecimal characters in the Hexadecimal code represents the intensity of the three primary colors (red, green, and blue). The primary color’s intensity ranges between 00 (the lowest intensity) and FF (the highest intensity).

Therefore, each hex code contains three sets of two characters in total. There can be any combination of ten numbers (0-9) and six letters (a-f) in these six characters. Hexadecimal codes consist of 16 symbols. The number of possible codes is 16,777,216. Let’s try figuring out a few of them.

Hexadecimal codes are up to three elements of two symbols each. Values range from 0 to 255 for each of the two-symbol elements.

Red value: The first element

Green value: The second element

The Blue value is the third element

This three-digit alphanumeric code is generated using a formula that turns each value into its own two-digit code. In hexadecimal code, the RGB value (224, 105, 16) is E06910.

What’s the reason? The numbering system used in base 16 is complicated. Read on to find out how it works. There are a couple of things you should know as a designer about this:

It is believed that people can perceive more than 16 million unique colors when they use hexadecimal codes.

Creating the code can be done through pickers and converters.

Instead of using numbers, why use hexadecimal? You could have one, two, or three numbers for every red, green, or blue value from 0 to 255. There is no limit to how many digits can be in the code – it could be as small as three or as large as nine. Especially for the humans doing the coding, this can confuse the systems reading the codes. In this way, every value will always be six symbols, reducing the chances of errors.

When you mix each primary color at its full intensity, you can figure out white’s hex color code. For example, #FFFFFF is the hex code for white. The hexadecimal code for black is #000000 since it lacks primary color. Ideally, you are looking for the red with the highest intensity and the two other primary colors with the lowest intensity. Therefore, red’s hex code is #FF0000. You can see some other combinations in the diagram below.

Try playing around with online tools like wheels and pickers to become more familiar with hex codes.

Make a note of the hexadecimal code for the one you like. This allows you to reuse the same colors across designs and channels, which is crucial for branding consistency.

How Do Hex Colors Work?

The hex mode uses the RGB model of early photography.

Using different combinations of red, green, and blue color values, it is possible to create virtually any color seen by the human eye.

In addition to almost every computer and phone screen, TVs, digital cameras, and projectors use the RGB color model.

A color value scale of 0 to 255 is used on the web and in most digital applications. You control the screen by indicating how much red, blue, and green should be displayed (or by telling a programmer). A viewer sees the color created by the combination of those colors.

The color you choose is up to you. There are 16,777,216 combinations in total, which far exceeds the ability of the human eye to distinguish them.

Having learned what HTML codes are and how to use them precisely, let’s see how they can be used.

How to Use HTML Color Codes

You can edit individual elements by inserting hex codes into your site’s HTML.

You might, for instance, want a paragraph to be blue. Simply set the property with the correct hex code in the style attribute of the paragraph element you wish to color. The code will look like this: <p style=”color:#FF0000″;>blue paragraph text</p>

You can also change the hue of your text, background, and other elements within your site by following this process.

Building a Site in Color

Your website can be memorable by using color to emphasize important elements, create brand recognition, and enhance content. You can add or change colors on your website to create a cohesive design now that you understand HTML codes.


What is a hex code used for?

Using the hexadecimal system, hex codes represent colors in RGB format by measuring the amounts of red, green, and blue in a specific shade. Color hex codes have been a key component of HTML for web design and remain a popular way to represent formats digitally.

What is the difference between RGB and Hex?

HEX and RGB represent the same thing – a red, green, and blue value. There is no informational difference between the two types; they are just different ways of communicating the same information. Both HEX and RGB are used to code colors. In HEX, characters are used to represent RGB values.
