What is RGB to HEX Conversion?
RGB to HEX conversion is the process of transforming RGB (Red, Green, Blue) color values into their hexadecimal (HEX) color code equivalent. RGB represents colors using three numbers from 0 to 255, indicating the intensity of red, green, and blue light, while HEX uses a six-digit code preceded by a # symbol, where each pair of digits represents the red, green, and blue components in hexadecimal format.
Our RGB to HEX converter tool allows you to easily translate between these two popular color formats used in web design, graphic design, and digital media. Whether you're coding websites, creating digital art, or developing applications, having the ability to convert between RGB and HEX formats is essential for consistent color representation across different platforms and tools.
How RGB and HEX Color Codes Work
RGB Color Model
The RGB color model uses the additive mixing of red, green, and blue light to create a wide range of colors. Each color channel has an intensity value ranging from 0 (no contribution) to 255 (full intensity).
Examples:
- Pure Red:
rgb(255, 0, 0) - Pure Green:
rgb(0, 255, 0) - Pure Blue:
rgb(0, 0, 255) - White:
rgb(255, 255, 255) - Black:
rgb(0, 0, 0)
HEX Color Code
HEX color codes represent the same RGB values but in hexadecimal notation (base 16, using digits 0-9 and letters A-F). Each pair of hexadecimal digits represents a color channel with values ranging from 00 to FF (equivalent to 0-255 in decimal).
Examples:
- Pure Red:
#FF0000 - Pure Green:
#00FF00 - Pure Blue:
#0000FF - White:
#FFFFFF - Black:
#000000
How to Use the RGB to HEX Converter
- Select Input Method: Choose between using the RGB sliders or manual RGB input, depending on your preference.
- Adjust RGB Values:
- Sliders Method: Move the sliders for red, green, and blue channels to set your desired color values from 0 to 255.
- Manual Input Method: Enter RGB values in one of the accepted formats (e.g., "rgb(255, 0, 0)" or "255, 0, 0").
- View Results: See a preview of your color and its corresponding HEX code displayed automatically.
- Copy the HEX Code: Click the copy button to copy the HEX color code to your clipboard for use in your projects.
- Try Common Colors: Click on any of the common color presets to quickly set the RGB values for standard colors.
RGB to HEX Conversion Formula
Converting from RGB to HEX involves transforming each component (R, G, B) from decimal (base 10) to hexadecimal (base 16) and then combining them into a single code. Here's the formula:
Where toHex() converts a decimal number (0-255) to a two-digit hexadecimal value (00-FF).
Example Calculation:
For the RGB color rgb(218, 112, 214) (a shade of orchid):
- R = 218 → DA in hexadecimal
- G = 112 → 70 in hexadecimal
- B = 214 → D6 in hexadecimal
Combining these values: #DA70D6
Common Applications for RGB to HEX Conversion
🎨 Web Design & Development
HEX color codes are widely used in CSS and HTML, making this conversion essential for web designers and developers who need to translate colors from design tools (which often use RGB) to web code.
📱 UI/UX Design
User interface designers frequently need to switch between RGB and HEX formats when moving between different design tools, prototyping software, and development environments.
📊 Data Visualization
When creating charts, graphs, and other data visualizations, being able to convert between color formats ensures consistent color schemes across different platforms.
🖼️ Digital Art & Graphic Design
Graphics professionals need to work with various color formats depending on the software they're using and the intended output medium (web, print, digital display, etc.).
Common Colors and Their RGB/HEX Values

| Blue | rgb(0, 0, 255) | #0000FF | |
| Yellow | rgb(255, 255, 0) | #FFFF00 | |
| Cyan | rgb(0, 255, 255) | #00FFFF | |
| Magenta | rgb(255, 0, 255) | #FF00FF | |
| White | rgb(255, 255, 255) | #FFFFFF | |
| Black | rgb(0, 0, 0) | #000000 | |
| Gray | rgb(128, 128, 128) | #808080 |
Frequently Asked Questions
Why do we use HEX codes for web design?
HEX codes are widely used in web design because they are compact and supported by all web browsers and CSS. They're more concise than RGB notation (e.g., #FF0000 vs rgb(255, 0, 0)) and were historically better supported in early web technologies. Today, both formats are equally supported, but HEX remains popular due to its brevity and convention.
Can I use 3-digit HEX codes?
Yes, some HEX codes can be shortened to 3 digits when each channel has repeated digits. For example, #FF0000 can be written as #F00, #00FF00 as #0F0, and #0000FF as #00F. This shorthand only works when both digits in each pair are the same (e.g., #ABC cannot be shortened because it represents #AABBCC).
What's the difference between RGB and RGBA?
RGBA is an extension of the RGB color model that includes an alpha channel (A) for transparency. The alpha value ranges from 0 (completely transparent) to 1 (completely opaque). In CSS, it's written as rgba(255, 0, 0, 0.5) for semi-transparent red. HEX has a similar extension with 8 digits (#RRGGBBAA), though RGBA is more commonly used when transparency is needed.
How do I convert HEX to RGB?
To convert HEX to RGB, you extract each pair of hexadecimal digits and convert them to decimal:
- Split the HEX code into three pairs: #RRGGBB
- Convert each pair from hexadecimal to decimal
- The three resulting values (0-255) are your RGB components
Are HEX color codes case-sensitive?
No, HEX color codes are not case-sensitive. #FF0000, #ff0000, and #Ff0000 all represent the same color (red). However, for consistency and readability, many developers and designers choose to use either all uppercase or all lowercase letters in their HEX codes.
