About the HSB to HEX Converter
What is HSB to HEX conversion?
HSB describes a color the way you'd describe it out loud: the Hue (which color it is, as a position from 0 to 360 degrees around the wheel), the Saturation (how vivid it is, 0 to 100%), and the Brightness (how light or dark, 0 to 100%). It's the model Photoshop, Figma, and most design apps put on their color sliders. A HEX code is the web's shorthand for the very same color — six characters like #3B82F6 that browsers understand in CSS and HTML. This converter takes your H, S, and B values, runs them through RGB, and hands back the HEX code along with the RGB, HSL, and CMYK equivalents and a live preview.
We built it for the moment you've nailed a color in a design tool and need to get it into code. Type the three numbers, or drag the sliders and watch the HEX update as you go. Prefer to start from a picker or an existing HEX? You can do that too, and the sliders snap to match. It all runs in your browser, so it's instant and nothing you enter is sent anywhere. Need to go the other direction? Our HEX to HSB converter does the reverse.
How to Use This Tool
- Enter your HSB values. Type the Hue (0–360), Saturation (0–100), and Brightness (0–100) into the boxes, or drag the three sliders. The preview and the HEX code update with every change.
- Grab the HEX code. The six-digit HEX sits right at the top of the results, ready to paste into your CSS or HTML, with the RGB, HSL, and CMYK versions listed underneath.
- Come at it from any angle. Already have a HEX, or want to use your system color picker or the eyedropper? Set the color that way and the HSB sliders move to match it.
- Explore and copy. Click any shade, tint, or harmony swatch to load it, then hit the copy button next to whichever value you need. Recent colors are saved locally so you can come back to them.
Common Use Cases
HSB is how designers think about color; HEX is what the browser actually wants. This tool is the bridge between the two. A few of the things people use it for:
- Shipping a design into code: You picked the perfect blue on Photoshop's HSB sliders — convert it to HEX and drop it straight into your stylesheet.
- Matching a brand guide: Some style guides list colors in HSB. This gives you the exact HEX so the live site matches the spec.
- Building lighter and darker variants: Nudge the Brightness or Saturation, grab the HEX at each step, and you've got a clean scale for buttons and hover states.
- Handing off between teams: Designers speak HSB, developers ship HEX — paste the values here and everyone ends up on the same color.
- Double-checking a conversion: Confirm that the HSB from your design app really does land on the HEX you expected before you commit it.
- Seeing how the models relate: Move one HSB slider and watch the HEX, RGB, and HSL all shift together — a quick way to build intuition.
Frequently Asked Questions
What is a HEX color code?
A HEX code is a six-character string like #3B82F6 that tells a browser how much red, green, and blue make up a color — two characters each, written in base-16. It's the standard way to set colors in CSS and HTML, which is why a color picked in a design app usually has to be converted to HEX before it reaches a website.
Why would I convert HSB to HEX?
Because design tools and the web speak different languages. Photoshop, Figma, and Sketch let you choose colors with HSB sliders because they're intuitive, but browsers don't read HSB — they expect HEX (or RGB/HSL). Converting bridges that gap so the color you designed is the exact color that ships.
Is HSB the same as HSV?
Yes. HSB (Brightness) and HSV (Value) are two names for one model, so whether your app labels the third slider B or V, you enter the numbers here the same way and get the same HEX out.
How do you convert HSB to HEX by hand?
First turn HSB into RGB: the Hue picks a base color, and Saturation and Brightness scale it into red, green, and blue values from 0 to 255. Then convert each of those three numbers into a two-digit base-16 (hexadecimal) value and join them behind a #. For example, hsb(217, 76%, 96%) becomes rgb(59, 130, 246), which is #3B82F6. It's a few steps with easy places to slip up, which is exactly why the calculator above helps.
What's the difference between HSB and HSL?
Both start from the same Hue, but they treat the rest differently. HSB pairs Saturation with Brightness, where 0% brightness is black. HSL pairs Saturation with Lightness, where 100% lightness is always white and 50% is the pure color. The same color carries different numbers in each. HSL is the one that's valid in CSS; HSB isn't, so HSB usually ends up converted to HEX or HSL for the web.
My HEX looks slightly different from the color in Photoshop — why?
The conversion itself is exact, so a HEX from this tool should match Photoshop for the same HSB input. Small differences almost always come down to rounding (HSB shown as whole numbers) or a color profile assigned inside the design app. On screen, monitor calibration can also make the same HEX look a touch different from one display to the next.
Can I just use HSB in my CSS instead of converting?
No — CSS has no hsb() or hsv() function, so browsers can't read HSB directly. Convert it to a HEX code, or use the hsl() value this tool also gives you, which CSS does support natively.
Is this converter free, and is my data private?
Completely free, with no sign-up and no limits. Everything is worked out in your browser with plain JavaScript, so the colors you enter are never uploaded or logged. Once the page has loaded, it keeps working offline too.
