HSL to HEX Converter
Free, accurate, and instant conversion. Preview your color in real-time on digital and print mockups.
Source Input HSL
/* CSS Variable */ --color-primary: #000000; /* Standard */ color: #000000; background-color: #000000;
Finalize Your Palette: HSL to Hex Conversion
You have used HSL to find the perfect shade—adjusting the saturation until it pops, and tweaking lightness for contrast. Now, you need to lock it in.
While CSS supports HSL, Hexadecimal remains the gold standard for compatibility, brevity, and copy-pasting between tools. This converter translates your dynamic HSL values into static, production-ready Hex codes.
Design Phase (HSL)
"Make it bluer." "Make it darker." HSL is the language of tweaking and experimentation.
The Calculation
We collapse the 3D HSL cylinder coordinates into linear RGB channels, then convert to Base-16.
Build Phase (Hex)
"#007AFF". Short, universal, and safe. The standard output for style guides.
Why convert if CSS supports HSL?
Consistency is key.
The Legacy Factor
Do you use generic email templates? Old Wordpress plugins? Specific data visualization libraries? Many of these "dumb" tools simply parse strings starting with `#`. They will break if you feed them `hsl(...)`. Hex is the safest bet for maximum compatibility.
Pro Tips for Production-Ready Colors
- • Keep an HSL reference for future tweaks—Hex is hard to mentally parse.
- • Use uppercase Hex (#FF5733) for consistency in style guides.
- • Test colors in both light and dark modes before finalizing.
- • Include WCAG contrast ratios in your documentation alongside Hex values.
Color Gamut: HSL wraps RGB
| Lightness | Result | Why? |
|---|---|---|
| 100% | #FFFFFF | Maximum light obliterates all hue/saturation. |
| 50% | Pure Color | This is the "equator" of the color sphere where colors are purest. |
| 0% | #000000 | Zero light is always black, regardless of hue. |

Frequently Asked Questions
Why convert HSL to Hex?
While CSS3 supports HSL directly, many older tools, design systems, and software (like Photoshop 'Web Safe' pickers) still prefer or require Hex codes. Converting to Hex ensures 100% compatibility across all digital platforms.
Is HSL to Hex accurate?
Yes, but with rounding. HSL is a continuous math model (decimals), while Hex is discrete (integers 0-255). Converting HSL(200.5, 50%, 50%) forces rounding to the nearest integer RGB value, which then becomes Hex.
Can I use percentages greater than 100%?
No. Saturation and Lightness are capped at 100% in the CSS standard. Our tool will automatically clamp values greater than 100 to 100.
What is the Hex code for transparent HSL (HSLA)?
It becomes an 8-digit Hex code (#RRGGBBAA). The last two digits represent the Alpha transparency (00 is transparent, FF is opaque).
How does Lightness affect the Hex code?
If Lightness is 0%, the Hex is always #000000 (Black). If Lightness is 100%, the Hex is always #FFFFFF (White). The color (Hue) only appears in the middle ranges.
Why is Hex more popular than HSL?
History. Hex has been around since the beginning of the web. HSL was added later. Also, Hex is shorter (7 chars) than HSL (16+ chars), saving bytes in code.
Does Hue wrap around?
Yes. 361° is chemically identical to 1°. Our converter handles any degree input.
Is this tool compatible with Sass/SCSS?
Yes. You can paste the resulting Hex code directly into your SCSS variables like $primary-color: #ff5733;.
How do greys work in HSL to Hex?
Any HSL value with 0% Saturation will result in a Hex code where R, G, and B pairs are identical (e.g., #808080).
What browser supports HSL?
All modern browsers (Chrome, Firefox, Safari, Edge) support HSL. However, if you need to support Internet Explorer 8 or older, you MUST convert to Hex.
How do I maintain color consistency across my design system?
Use HSL for design exploration (adjusting shades easily), then convert to Hex for your final style guide. Document both values—HSL for designers and Hex for developers.
Can I use negative Hue values?
Yes. Negative values wrap around the color wheel. -30° is the same as 330°. Our converter normalizes any input to the 0-360° range automatically.
