Accurate HEX to Pantone color converter. Supports HEX, RGB, CMYK inputs. Delta E 2000 algorithm for precise matching. HEX, RGB, and CMYK to Pantone — right in your browser A Chrome extension for designers, print buyers, and anyone who needs to match a screen color to a real Pantone swatch. Enter a color in any common format, get the 5 closest Pantone references with a similarity score for each. No account, no upload, no waiting. If you have ever opened three tabs trying to figure out what Pantone is closest to #2A5DB0, this is the shortcut. What this hex to pantone converter actually does You type or paste a color. The extension converts it to LAB color space, then compares it against more than 14,000 Pantone references using the CIEDE2000 (Delta E 2000) formula — the same perceptual color-difference math that color scientists and print labs use. The 5 closest matches come back in milliseconds, each with a similarity percentage so you can judge for yourself how close the match really is. Why this matters: a simple distance between RGB values does not match how human eyes perceive color difference. Two color pairs can sit the same RGB distance apart and look completely different to a real viewer. CIEDE2000 corrects for that. So when this hex to pantone conversion tool reports a 97% match, that number reflects what your eye would say, not what a calculator would say. Four ways to enter a color The extension works as a hex to pantone converter, an rgb to pantone converter, and a cmyk to pantone converter — same window, one click to switch modes. 🌐 HEX. Paste a hex code from your CSS, your design file, or a brand guideline. Both formats work: FF5733 or #FF5733, lowercase or uppercase. This is the hex color to pantone path most web designers use, since hex is what comes out of every browser color picker and every dev tool. 🖥 RGB. Enter R, G, and B values from 0 to 255. Useful when you're working in software that reports RGB (Photoshop, Figma, Sketch) and need to convert rgb to pantone for handoff to a printer. 🖨 CMYK. Enter C, M, Y, K percentages from 0 to 100. The cmyk to pantone converter handles colors that originated in print-first software, where CMYK is the working space. If a client sent you a CMYK breakdown and the press now needs a spot color, this is how you get there. 💧 Eyedropper. Sample a color from anywhere on your screen. Useful for matching out of an image, a screenshot, or a brand asset where you don't have the source file. Click, sample, see the closest Pantone matches. Why five matches, not one Color matching is not a problem with a single right answer. The closest mathematical Pantone might not be the best fit for your specific situation. Uncoated paper shifts colors differently than coated. Warm lighting changes how a swatch reads. Some Pantones simply look better in certain contexts than others. So instead of forcing one result, this hex to pantone colour converter shows the top 5 ranked by similarity. You see 97%, 95%, 93%, 91%, 89% — and you decide which one fits your project. That is how a professional would think about it; the extension just gives you the shortlist faster. Use cases 📤 Web-to-print handoffs. A client gives you a CSS variable. The printer needs a Pantone. You convert hex to pantone in two clicks, send three options to the printer, and let them pick the one their press can hit cleanly. No more emailing screenshots back and forth. 🔍 Brand color audits. Marketing teams maintaining consistency between digital and print need to verify that a CSS hex actually lines up with the Pantone in the brand book. Drop the hex in, see if it's a tight match or if there is drift worth flagging. 🧪 Reverse-engineering colors. You have a competitor's logo, a packaging photo, or a screenshot of a brand you admire. Use the eyedropper, then match hex to pantone — now you have a real reference for the next meeting. 🖨 Print production. Prepping files for press and need to convert cmyk to pantone for a spot color callout? The cmyk to pantone converter gives you the closest standardized reference without leaving the browser. 📱 Digital-to-physical handover. Web designers moving a digital design to printed materials regularly need to convert rgb to pantone for swatches the press can mix. The rgb to pantone converter handles this path directly, and the rgb to pantone matching system gives you ranked options so you can compromise intelligently between fidelity and printability. Who uses this extension - 🎨 Graphic designers working across print and digital - 🏷️Brand managers tracking color drift between channels - 🖨️Print production specialists prepping files for press - 📦 Packaging designers picking spot colors - 📣 Marketing teams chasing color consistency across campaigns - 💻 Web developers translating design tokens to physical media - 👀 Anyone who has ever opened a Pantone book and squinted Why this hex color converter to pantone exists Most online converters do the bare minimum: a single match, often based on a crude RGB-distance formula that ignores how humans actually see color. The result is a "match" that looks wrong on the swatch book. Other tools are buried inside paid software you don't have a license for, or live on slow, ad-stuffed websites that take a tab to load every time. This is a small extension that does one thing well: convert hex to pantone (and CMYK, and RGB) using a perceptually accurate formula, instantly, in the tab you are already in. FAQ Is this an official Pantone tool? No. The extension is an independent matching tool. Pantone is a trademark of Pantone LLC. This tool helps you find the closest Pantone reference to a color you have — it does not replace official Pantone swatch books, which remain the authoritative reference for press production. How accurate is the rgb to pantone matching system? Accuracy depends on the source color. Colors that sit inside the Pantone gamut typically return matches above 95%. Very saturated or unusual hues — neons, deep cyans — may show lower top matches simply because no Pantone reference exists that is truly close. The similarity percentage is honest about that: when you see 82%, the closest Pantone is not very close, and you should know before sending to print. Does it work offline? Yes, once installed. The conversion runs locally in your browser. Nothing is uploaded. What if I paste a hex without the #? Works. The hex color converter to pantone accepts FF5733, #FF5733, ff5733, and #ff5733. Use whichever format your source gives you. Can I convert rgb to pantone for screen-only work? You can, but spot color references like Pantone are designed for print, not screen. If your final medium is digital, you usually do not need a Pantone at all — RGB or HEX is the working color space. The convert rgb to pantone path makes sense when there is a physical output somewhere in the pipeline.
