What exactly is hex color? Learn the definition of hex colors, and discover how to use them in your designs.
Hex colors allow designers to create visual appeal and convey powerful emotions. They ensure consistency, accessibility, and adaptability.
Let’s explore the world of hex colors and answer the following questions: What are Hex codes? How are they used? And what advantages do they offer designers?
What Are Hex Colors?
The term “hex” comes from the word “hexadecimal,” which is a numeral system with a base of 16. You can think of them like RGB color codes. They represent the amount of Red, Green, and Blue (or RGB values.)
What is a hexadecimal notation? If you are unfamiliar with this term, you’re not alone. The decimal system we’re all familiar with utilizes 10 digits. In a hexadecimal system, digits are represented using standard symbols such as 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 for the corresponding values, and the first six letters of the alphabet—A, B, C, D, E, F—for values 10 through 15.
Hex colors are a way of representing primary colors from the color wheel through hexadecimal values. A hexadecimal notation follows the “pair of characters” format #RRGGBB, where RR is the red value, GG is green value, and BB is blue value. These hexadecimal integers can be in a range of 00 to FF to specify the intensity of the color.
A simple example of a Hex code is #FF0000. This color is pure red, because the red component is at its max value of FF and the green and blue components are at their lowest of 00.
Soon, you’ll be an expert at using these RGB color values!
How to Use Hex Colors and RGB Color Values
What is hex color’s use? Using hex codes to represent different colors is an easy way to differentiate between colors. Once you understand how they work, you can easily change red, blue, or green values to create different (and exact) shades using hexadecimal notation.
There are many color picker tools that can help you find the perfect hex code. Most design apps have them built in using the Eyedropper tool. Google has a wonderful color picker that is extremely user friendly.

Advantages of Using Hex Colors in Design
1. Consistency
Hex colors provide a standardized way to communicate colors across different platforms and devices. Since they use a combination of letters and numbers, they can be easily understood by designers and developers, globally ensuring the basic colors of your design carry through.
2. Wide Range of Colors
With millions of possible combinations, hex colors offer an extensive palette for designers to choose from. This enables them to bring their creative visions to life and select the perfect shade or hue for their design projects.
3. Compatibility Across Software Applications
Hex colors are widely supported across various design software, including graphic editing tools, web development platforms, and content management systems. This ensures that the chosen colors will appear consistently across different mediums and maintain their desired appearance using the proper hex code.
Using Hex Colors Effectively + Color Design Tips
Using hex colors effectively can greatly enhance the overall aesthetic and appeal of your designs. One tip is to choose colors that create a harmonious, visually-pleasing palette.
This can be achieved by using a color wheel or color theory to select colors that are complementary or analogous. Additionally, it’s important to consider the context and purpose of your design when choosing hex colors.
For example, bright and bold colors may be attention-grabbing and suitable for certain types of designs, while muted and neutral tones may be more appropriate for a subdued and elegant look.
Experimenting with different combinations and shades of hex colors can help you create visually-striking designs that effectively convey your intended message.
Here are some handy tips for creating beautiful color harmonies.
Understand Color Psychology and Color Theory
Different colors evoke different emotions and have psychological effects on viewers. Before selecting hex colors for your design, consider the mood and message you want to convey and choose colors accordingly.
Color possibilities are endless, and this can really help you refine your vision. There are lots of resources for researching color meanings. Make sure you listen to experts in this space, and do proper research. Color meanings can change from country to country.
Test Color Combinations
Experiment with different hex color combinations to ensure they complement each other harmoniously. Tools like color palette generators can assist in finding pleasing color schemes and help you to generate a list of colors that are perfect for your design.
Check Contrast Accessibility
Ensure that the contrast between the background color and the text, or other elements, is strong enough to maintain readability, especially for websites or applications that need to adhere to accessibility standards.
Optimize for Web
When using hex colors for web design, keep in mind that some colors may appear differently on different screens and browsers. To ensure consistency, test the colors on various devices and browsers to achieve the desired effect.
Web-Safe Colors
Web-safe colors are limited to a palette of 216 specific colors, consisting of six shades each of red, green, and blue. The limitations on web-safe colors have become less relevant in recent years with the advancement of technology and the use of more sophisticated color management systems.
Nonetheless, the concept still serves as a guideline for designers to choose colors that are more likely to appear consistently across multiple platforms.
Color Style Sheets
A color style sheet can be used to ensure consistency and enhance the visual appeal of a website or application. It serves as a guide for selecting and applying colors throughout the design, ensuring a cohesive and professional look.
Here are a few reasons why creating a color style sheet can be beneficial:
1. Consistency
A color style sheet helps maintain consistency in the use of colors across different pages or sections of a website. By defining a set of colors to be used for various elements such as headers, backgrounds, buttons, and links, you create a unified visual experience for users.
2. Branding
If you are designing a website or application for a brand, a color style sheet can help ensure that the chosen colors align with the brand’s identity and guidelines.
Consistently applying brand colors throughout the design reinforces a brand’s recognition and strengthens its visual presence.
3. Accessibility
Certain color combinations can be difficult to read for people with visual impairments or color blindness. By creating a color style sheet, you can define color combinations that meet accessibility guidelines, providing a better user experience for a wider audience.
Foreground colors and background colors should work together harmoniously and be easy to read in text applications.
4. Efficiency
Having a predefined color style sheet saves time and effort in the design process. Instead of manually selecting colors for each element, you can refer to the style sheet and quickly apply the appropriate colors.
This ensures a more efficient workflow and reduces the chance of inconsistencies or mistakes.
5. Adaptability
In the future, if you need to make changes to the color scheme of your design, having a color style sheet makes it easier to update and maintain. By modifying the style sheet, you can ensure that the changes are applied consistently and throughout the entire design.
Overall, creating a color style sheet provides a clear structure and guidance for selecting and applying colors, resulting in a more visually-appealing and cohesive design.
How Many Hex Colors Are There?
In standard #RRGGBB notation, each RR, GG, and BB can contain 256 different values, ranging from 00 to FF. So, that means there are 256^3 color combinations available, or 16,777,216!
An interesting side note is that many modern browsers also support transparency. This means that an entirely new set of color codes, in the form of #AARRGGBB, raising the number to 256^4, or 4,294,976,296!
It’s important to keep in mind that the addition of the transparency does not indicate that there are extra colors, since solely adding transparency does not change the color. This merely adds more information and more available color codes depending on transparency/level of opacity.
Leave a Lasting Impact
Hex colors offer a flexible and standardized way for designers to represent an extensive range of colors in a variety of formats using red, blue, and green values—primary color values.
By understanding how hex colors work and following best practices, designers can create visually-captivating, cohesive designs that effectively communicate their message and leave a lasting impact on their audience.
