How to Convert HEX to Pantone: A Step-by-Step Guide

Every color on a digital screen has a HEX code — a six-character identifier like #C8102E that tells your monitor exactly how much red, green, and blue light to emit. But when that color needs to go to print, particularly for brand-critical work, you'll need to find its closest Pantone PMS equivalent.

This guide explains exactly how that conversion works, what its limitations are, and how to get the most accurate result for your print projects.


What Is a HEX Color Code?

A HEX code is a hexadecimal representation of an RGB color. Each pair of characters represents one color channel:

#C8102E
 ^^  → Red:   C8 = 200
   ^^ → Green: 10 = 16
     ^^ → Blue:  2E = 46

So #C8102E is rgb(200, 16, 46) — a deep red. HEX codes are used everywhere in digital design: CSS, Figma, Photoshop, brand guidelines, and design systems.

Tip

Shorthand HEX codes like #FFF or #C8E expand to #FFFFFF and #CC88EE. Most Pantone converters accept both formats.


Why You Need to Convert HEX to Pantone

HEX colors exist in RGB color space — designed for screens that emit light. Pantone colors are pre-mixed printing inks — designed for paper that reflects light. These are fundamentally different systems.

When you send a file to a professional printer with only HEX or RGB values, the printer must guess how to translate your screen color into physical ink. This introduces variation. Different printers will produce different results.

Specifying a Pantone color eliminates this guesswork. The printer uses a standardized pre-mixed ink — the same ink, every time, everywhere.

Common scenarios where you need HEX to Pantone:

  • Your brand guidelines specify a HEX code but your printer needs a Pantone reference
  • You're designing packaging, merchandise, or signage that requires color consistency
  • A client sends you a website color and you need to match it for print collateral
  • You're updating brand guidelines to include both digital (HEX) and print (Pantone) values

How the Conversion Works

HEX to Pantone conversion workflow diagram

No algorithm can produce a perfect HEX-to-Pantone conversion because they represent fundamentally different color systems. What converters do is find the closest available Pantone color using a mathematical distance formula.

Here's the process step by step:

Step 1 — Parse the HEX to RGB #C8102Ergb(200, 16, 46)

Step 2 — Compare against the Pantone database Every Pantone color has a known HEX/RGB approximation. The algorithm calculates the perceptual distance between your input and every color in the database.

Step 3 — Rank by similarity Colors are ranked from closest to furthest. The top result is the "best match" — but it may still be visually different, especially for saturated or unusual colors.

Step 4 — Return top matches A good converter returns the top 5 matches so you can choose based on context — for example, preferring a slightly different hue that better fits your brand's overall palette.

Warning

The algorithm limitation: Perceptual color distance in RGB space doesn't perfectly match how human eyes perceive color differences. A weighted RGB formula (giving more weight to green, which eyes are most sensitive to) produces better results than plain Euclidean distance — which is the approach PantoneConverter.com uses.


Step-by-Step: Converting HEX to Pantone

Step 1 — Find your HEX code

Your HEX code could be in:

  • Figma or Sketch (click the color picker, copy the HEX value)
  • Brand guidelines PDF (look for the digital/web color specification)
  • CSS stylesheet (color: #C8102E)
  • Photoshop color picker

Make sure you have the full 6-character code. If you only have an RGB value, use our RGB to Pantone converter instead.

Step 2 — Enter it into the converter

Go to HEX to Pantone Converter. Paste your code with or without the # prefix — both work.

The large color preview box will immediately show your color. This is useful for a sanity check — if the preview looks wrong, double-check your HEX code.

Step 3 — Choose Coated or Uncoated

Before reviewing results, select the correct paper type:

  • Coated (C) — glossy or silk paper, packaging, magazines. Colors appear more saturated and vibrant.
  • Uncoated (U) — matte paper, letterheads, notebooks. Colors appear softer and slightly duller.
Tip

Not sure which to use? Ask your print supplier what paper stock they're using and whether it's coated or uncoated. When in doubt, request a printed proof with both variants.

Step 4 — Review the top 5 matches

Don't automatically take the #1 result. Look at all five:

  • Similarity % — higher is closer, but even 90%+ can be visually noticeable
  • Color swatch — compare the rendered swatch to your original color
  • Pantone name — recognizable names like "Reflex Blue" or "Process Black" are industry standards your printer will know immediately
Original: #C8102E
#C8102EInput HEX color
Pantone 186 C
#C8102E100% match — this is Pantone's exact HEX approximation for 186 C

Step 5 — Verify with a physical swatch book

This step is non-negotiable for professional print work. Your monitor displays colors using backlit pixels — Pantone colors are printed inks on paper. They will always look different on screen.

The Pantone Formula Guide (Coated & Uncoated) is the industry standard reference. If you work with print regularly, it's worth owning one. They're updated periodically as Pantone adds new colors.


Common HEX to Pantone Mistakes

Mistake 1 — Using the wrong substrate variant Specifying Pantone 186 C when the job is on uncoated paper. Always match C/U to your actual paper.

Mistake 2 — Trusting screen previews The Pantone swatch you see on screen is an RGB approximation of the real ink. It's directionally correct but not accurate. Physical swatch is the only truth.

Mistake 3 — Ignoring the similarity score A 75% match means the colors are noticeably different. If no Pantone color matches above 85%, consider whether spot Pantone is the right choice — sometimes a well-calibrated CMYK mix is more accurate for unusual hues.

Mistake 4 — Forgetting that some colors have no good Pantone match Very saturated digital colors — electric blues, neon greens, pure white — often don't have close Pantone equivalents in the standard Solid library. Check the Pastels & Neons library for fluorescent colors.


HEX to Pantone for Brand Guidelines

If you're creating or updating brand guidelines, you should document colors in all three systems:

FormatExampleUsed For
HEX#C8102EWeb, digital, CSS
RGB200, 16, 46Screen design tools
CMYK0, 92, 77, 22General commercial print
Pantone186 CBrand-critical spot color print

This ensures any designer or vendor can work with your brand color in any context without needing to convert themselves.


Frequently Asked Questions

No — it finds the closest available Pantone color, not a mathematically perfect match. HEX colors exist in RGB color space (designed for screens), while Pantone colors are physical printing inks. The two systems have different color gamuts, meaning some digital colors have no precise Pantone equivalent.
If you have a Pantone Connect subscription, you can use the built-in color libraries. Otherwise, find the closest Pantone match using PantoneConverter.com, then in Illustrator go to Window → Swatches → Open Swatch Library → Color Books → PANTONE+ Solid Coated, and search for your Pantone number.
Every Pantone color has an official HEX approximation published by Pantone. You can look up any Pantone color's HEX equivalent using our Pantone to HEX converter or the Pantone Color Finder. Note that this HEX value is an approximation — the true Pantone color can only be seen on a physical swatch.
Because screens emit RGB light while Pantone colors are printed inks. Your monitor cannot accurately display Pantone colors — it can only show an approximation. This is why physical Pantone swatch books are the industry standard for color approval.
