What is a hex color code?
A hex color code is typically a six-digit code that combines numbers and letters and begins with a hash symbol (#), where each pair of digits represents the intensity of red, green, and blue. The term "hex" in hex code comes from "hexadecimal," a numbering system that uses 16 symbols: 0-9 and A-F.
Hex colors are derived from the RGB color model, which blends varying intensities of red, green, and blue to produce a wide range of colors. To create a hex code, the RGB (which stands for red, green, and blue) color values are converted into this number system. For example, the RGB color (224, 105, 16) becomes the hex code E06910.
Hex color codes offer a standardized method for representing colors across different platforms and devices. They use hexadecimal values to represent primary colors from the color wheel. Hex codes are universal and can be easily interpreted by designers and developers, ensuring consistent color representation in designs.
History of hex codes
The hex color code system originated during the early development of computer graphics. As computers transitioned from basic black-and-white screens to more advanced color displays, there was a growing need to standardize and define colors. The hexadecimal system, which was already used in computing for tasks like memory addressing, emerged as an effective solution. Its compactness and efficiency made it ideal for the purpose. The system was eventually adopted in HTML and CSS, making it a core element of web design and paving the way for the rich and color-filled user experiences we see today.
This shift to hex codes also allowed for greater consistency across various digital platforms, ensuring that colors appeared the same regardless of the device or software used. As a result, it allowed designers to lay the foundation for more dynamic and visually appealing websites.
What is the difference between hex codes and RGB?
The main difference between hex codes and RGB lies in their format. Hex color codes are always six digits long, making them predictable and consistent, which is why programmers often favor them. On the other hand, RGB values can range from three to nine digits, offering more flexibility but also requiring more attention to detail.
While hex codes are commonly used in web design, they are not mandatory. When coding in HTML, you can opt for RGB values or even color names instead. However, it’s important to note that just because you can use RGB values or names doesn’t mean you should. To avoid potential errors in your project, using a color hex wheel picker or converter is recommended to generate the desired hex code. This reduces the risk of future coders misinterpreting or manually converting the colors, ensuring your web page retains its intended look.
How do hex color codes work?
Hex colors are derived from the RGB color model, and a hexadecimal notation is used to indicate the blend of red, green, and blue (RGB) in a color. They are represented as #RRGGBB, where each RR, GG, and BB can contain 255 different values. This range specifies the intensity of each color.
The concept behind the model is that you can create almost any color by combining varying amounts of red, green, and blue color values. This model is used in digital screens as well as in devices like digital cameras and video projectors. With over 16.7 million possible combinations of these values, there is a wide range of colors to choose from. In fact, this number exceeds the human eye's ability to differentiate between each unique shade.
Structure of hex color codes
A hex color code follows a structure:
- The first two digits represent the red component
- The next two digits represent the green component
- The last two digits represent the blue component
For example, in the hex code #78C8FF:
- 78 indicates the red intensity
- C8 indicates the green intensity
- FF indicates the blue intensity
Conversion from RGB to Hex
RGB values, which range from 0 to 255 for each color, can be converted to hex by following these steps:
- Take the decimal value of the red, green, and blue components.
- Convert each value to its hexadecimal equivalent.
- Combine the hex values into a single hex code.
For example, to convert the RGB value (120, 200, 255) to a hex code:
- The red value 120 converts to 78
- The green value 200 converts to C8
- The blue value 255 converts to FF
So, the RGB value (255, 87, 51) is represented as the hex code #78C8FF.
Benefits of using hex color codes in graphic design
Before using hex color codes for your designs, it is important to understand their significance. Here are some compelling benefits:
1. Consistency
Hex colors provide a universal language of defining colors, making sure the exact same color appears on different devices, browsers, and operating systems. This consistency is essential for maintaining the integrity of designs across diverse platforms, whether it’s on a computer, smartphone, or tablet. By using hex codes, designers can be confident that the right color will be displayed consistently, regardless of where it's viewed.
2. Ease of use
Working with hex codes is simple because they consist of a hash symbol (#) followed by a combination of six letters and digits. This makes them compact and easy to write or copy-paste. Unlike other color systems, such as RGB, which requires multiple numbers (three values between 0 and 255), hex codes offer a more concise way to specify a color, which speeds up the design process.
3. Variety of colors
With millions of color combinations available, hex codes provide designers with a vast palette to work with. This allows them to materialise creative ideas and select the ideal shade or hue for their design projects.
4. Precision and accuracy
Hex codes allow designers to specify colors with a high degree of precision. Since each component of the color (red, green, and blue) is represented by two digits in the hex code, designers can achieve the exact shade or tone they want. This level of accuracy is significant for branding and when replicating specific color palettes across different media.
5. Wide compatibility
Nearly all digital platforms, from web browsers to design software, including graphic design tools, content management systems, and web development tools like HTML and CSS, support hex codes. This makes hex colors the go-to option for designers and developers, as they can be easily integrated into any project without worrying about compatibility issues.
6. Flexibility
Hex codes offer an enormous range of color possibilities. This flexibility allows designers to choose from an extensive palette of colors to match their creative vision, making it easy to find the perfect hue for any project. Whether working with vibrant tones or muted shades, hex codes provide versatility in designing with virtually any color imaginable.
7. No conversion needed
One of the major advantages of hex codes is that they don’t require conversion from one format to another. While RGB values (representing colors in terms of red, green, and blue intensity) sometimes need to be converted to hexadecimal or vice versa, hex codes are direct and ready to use. This simplifies the design process and eliminates the possibility of errors or inconsistencies caused by incorrect conversions.
How to read hex color codes

While hex codes may appear complex with their alphanumeric combinations, understanding them can help you become an expert in color precision and allow you to customize colors for your designs effectively. Here’s how they work:
1. Hexadecimal system
Hex color codes use the base-16 numbering system, which includes numbers (0-9) and letters (A-F). Each character represents four bits of information, known as a "nibble." For example, #FF5733 is a hex code for a shade of orange.
2. Structure of hex codes
A hex color code consists of six characters, typically grouped in pairs. These pairs represent the intensity of the three primary colors, red (R), green (G), and blue (B):
For example, in #FF5733:
- FF represents the highest intensity of red
- 57 stands for a moderate amount of green
- 33 indicates a small amount of blue
3. Understanding the scale
Since hex codes derive from the RGB model, understanding the intensity of each is critical to creating the right code.
- A code like #FF0000 represents full red (FF), no green (00), and no blue (00), creating a pure red color.
- A code like #00FF00 represents full green, no red, and no blue, resulting in a pure green color.
- A code like #0000FF represents full blue, with no red or green, giving a pure blue color.
How to use hex colors effectively?
Colors have the power to evoke a wide range of emotions and influence how viewers perceive a design. Before choosing hex colors for your project, it’s essential to consider the mood and message you want to communicate and select colors that align with those intentions.
The possibilities for colors are vast. Many resources are available to help you understand the meanings behind different colors. Be sure to consult experts in color psychology and conduct thorough research to make informed choices.
1. Experiment with color combinations
Test different hex color combinations to ensure they complement each other. Tools like color palette generators can help you identify appealing color schemes and create a list of colors that suit your design.
2. Pay attention to the contrast
Make sure there is enough contrast between the background color and text or other elements to ensure readability. This is particularly important for websites or applications that need to meet accessibility standards.
3. Optimize for the web
When using hex colors in web design, remember that some colors may look different across various screens and browsers. To maintain consistency, it's important to test the colors on different devices and browsers to ensure they produce the desired effect.
4. Use web-safe colors
Web-safe colors are limited to a palette of 216 colors, made up of six shades each of red, green, and blue. While the importance of web-safe colors has diminished with technological advancements and improved color management systems, the concept still provides a useful guideline for designers to select colors more likely to display consistently across various platforms.

When designing for an existing website or trying to match other elements, it's essential to know the hex colors used on the site. A reliable color picker tool can be incredibly helpful, especially for creating attention-grabbing marketing materials.
ImageColorPicker allows you to upload any image and identify the hex colors it contains.
Another useful tool is the ColorPick Eyedropper, a Google Chrome extension that lets you easily find the hex color of any element on a webpage. If you spot a color you like on a site, simply use the Eyedropper to identify it.
If you're selecting imagery and other elements for the site, finding assets matching your chosen hex color palette works best. On iStock, you can filter search results by hex color. Enter the hex code or select a color using their picker, then add your search keywords. The site will return images that closely match the color you've chosen.
3. Be careful with color banding

With 16 million possible colors, hex color codes offer a wide range of options for creating contrasts. However, since each pixel must display a unique color, hex codes don't allow smooth transitions between shades.
When web designers use hex colors to create gradients, the result can often be unexpected, leading to distinct color bands instead of a smooth blend. This phenomenon, known as color banding, is more likely to occur on older devices that can't display millions of colors.
In modern CSS, it's possible to program gradients in a way that minimizes color banding. On newer screens, color banding is most noticeable in natural gradients, such as skies or rainbows, where the many subtle color variations visible to the naked eye are compressed to save file space.
