Common RGB to HEX Examples
| Color | RGB | HEX |
|---|---|---|
| Red | rgb(255, 0, 0) | #FF0000 |
| Green | rgb(0, 255, 0) | #00FF00 |
| Blue | rgb(0, 0, 255) | #0000FF |
| White | rgb(255, 255, 255) | #FFFFFF |

| Purple | rgb(128, 0, 128) | #800080 |
Why Convert RGB to HEX
RGB and HEX represent the exact same colors — they're just two different notations for the same underlying value. RGB uses three decimal numbers from 0 to 255, which maps naturally to how screens mix red, green, and blue light. HEX encodes those same three values as a six-character base-16 string, which is more compact to type and paste into a stylesheet or design tool.
The reason you need to convert is that different tools speak different dialects. CSS accepts both, but most design handoffs, brand guidelines, and color pickers report colors in one format or the other. A designer picks a color visually and sees rgb(255, 87, 51) — a developer needs #FF5733 to drop into a Tailwind config or a CSS variable. This tool bridges that gap instantly.
Because the conversion is pure math — no image processing, no file uploads — it runs entirely in your browser with no server involved. Adjust the sliders, type values directly, or use the native color picker, and the HEX code updates in real time.
How RGB to HEX Conversion Works
Each RGB value is a decimal number from 0 to 255, and HEX encodes that same number in
base 16 instead of base 10. Converting just means taking each of the three RGB numbers
(red, green, blue) and writing it as a two-digit hexadecimal value, then joining all
three together after a #.
For example, the color rgb(255, 87, 51) converts digit by digit: 255 in decimal is FF in hex, 87 is 57, and 51 is 33. Joined together, that gives the HEX code #FF5733.
Use Cases
Web Design
Pick brand colors visually, then grab the exact HEX code to use across a site's design files.
CSS Development
Convert RGB values from a design handoff straight into the HEX codes CSS stylesheets expect.
Graphic Design
Match colors across design tools that report RGB with the HEX values logos and icons need.
UI/UX Design
Translate prototype RGB swatches into HEX codes ready to hand off to a development team.
RGB vs HEX: Format Comparison
| Feature | RGB | HEX |
|---|---|---|
| Format | Decimal (0–255 per channel) | Hexadecimal (00–FF per channel) |
| Example | rgb(255, 87, 51) | #FF5733 |
| CSS Support | Yes — rgb() and rgba() | Yes — #RRGGBB and #RGB |
| Transparency | Yes — via rgba() | No (use rgba or 8-digit hex) |
| Human Readable | Easier to understand channels | Compact, standard for web |
| Common Use | Code, APIs, design tools | CSS, HTML, design files |
| Color Accuracy | Identical | Identical |
| Free to Use | Yes | Yes |
Both formats represent the same color — the choice comes down to which format the tool or codebase in front of you expects. HEX is the default for CSS and HTML; RGB is common in design tools, APIs, and anywhere transparency via rgba() is needed.
Frequently Asked Questions
What is RGB?
RGB stands for Red, Green, Blue — a color model that defines a color by mixing three light values, each ranging from 0 to 255, to produce the full range of colors a screen can display.
What is HEX?
HEX is a base-16 (hexadecimal) representation of an RGB color, written as a six-character code like #FF5733. The first two characters represent red, the middle two represent green, and the last two represent blue.
Why convert RGB to HEX?
Different tools and codebases expect colors in different formats — CSS, HTML, and most design software commonly use HEX, while sliders, code, and some APIs report colors as RGB. Converting lets you move a color between the two without guessing.
How do I find the HEX code of a color?
Drag the R, G, and B sliders above (or type exact values) until the preview matches your color, or use the native color picker to choose it visually — the HEX code updates instantly either way.
Is RGB the same as HEX?
They represent the same underlying color, just in different notations. RGB uses three decimal numbers from 0–255, while HEX encodes those same three values as a six-digit hexadecimal code. Converting between them never changes the actual color.
Can I use HEX codes in CSS?
Yes. HEX is one of the most common ways to specify color in CSS, for example background-color: #FF5733;. RGB values work in CSS too, written as rgb(255, 87, 51).
