How to Convert RGB to Hex Color Code Easily (Step-by-Step Guide)
If you work in graphic design, UI/UX, web development, or digital branding, you’ve likely seen RGB and Hex color codes everywhere. RGB is commonly used in screens and digital displays, while Hex codes are widely used in web design and CSS styling. Knowing how to convert RGB to Hex color code easily is an essential skill for anyone working with digital colors.
Whether you are building a website, designing an app interface, or extracting shades using a color picker from image, converting RGB to Hex ensures you can apply colors accurately across platforms. In this guide, we’ll explain RGB and Hex formats, show the easiest conversion method, and explain how tools like Ralpel can make the process faster.
What is RGB Color Code?
RGB stands for Red, Green, and Blue. It is a color model used mainly for digital screens such as monitors, televisions, and mobile devices.
RGB values are written in this format:
RGB(255, 0, 0)
Each number represents the intensity of red, green, and blue on a scale from 0 to 255. When combined, they create millions of possible colors.
Example:
RGB(0, 0, 0) = Black
RGB(255, 255, 255) = White
RGB(0, 255, 0) = Bright Green
RGB is popular because it matches how digital displays create color using light.
What is Hex Color Code?
Hex codes are written using hexadecimal (base-16) values. A Hex color code always begins with a # symbol, followed by six characters.
Example:
#FF0000
Hex codes are commonly used in:
Website CSS styling
UI design systems
Digital branding palettes
HTML themes
Hex codes are easy to copy, share, and store in design guidelines.
Why Convert RGB to Hex?
There are several practical reasons why converting RGB to Hex is useful, especially for designers and developers in Ireland working on modern web projects.
Common Reasons:
Web developers often need Hex codes for CSS
Designers may receive RGB values from Photoshop or Figma
A color picker from image tool may provide RGB output first
Branding requires consistent formatting across platforms
Hex is the most standard color format for websites, so conversion becomes essential for smooth workflow.
How to Convert RGB to Hex Color Code Easily (Manual Method)
To convert RGB to Hex manually, you need to convert each RGB value (0–255) into a two-digit hexadecimal number.
Step-by-Step Example:
Convert RGB(255, 99, 71) into Hex.
Step 1: Convert Red (255)
255 in hex = FF
Step 2: Convert Green (99)
99 in hex = 63
Step 3: Convert Blue (71)
71 in hex = 47
Step 4: Combine them
Hex code becomes:
#FF6347
That is the final Hex output.
Quick RGB to Hex Conversion Table
Here are a few common conversions:
RGB(255, 0, 0) = #FF0000
RGB(0, 255, 0) = #00FF00
RGB(0, 0, 255) = #0000FF
RGB(255, 255, 255) = #FFFFFF
RGB(0, 0, 0) = #000000
This is helpful when working with branding or web design projects.
