RAL to Hex Converter
RAL to Hex Converter. Type a name like RAL 5010 into RAL Name and the RAL to Hex Converter instantly looks up its approximate Hex Output. Enter your cyan, magenta, yellow, and key percentages into the cmyk to hex converter to get the matching hex color for screen display.
Need the on-screen version of a paint swatch? This RAL to Hex Converter turns a four-digit RAL code into a hex color code you can paste into CSS, a Figma file or a brand sheet, so the colour on your website matches the finish on the wall. Type the code, click the Convert button, and read the result next to its RGB, HSL, HSB and CMYK values and a live swatch.
What Is a RAL to Hex Converter?
A converter like this is a lookup tool that translates a RAL Classic code into the hexadecimal notation that browsers use. RAL is the standardized color system behind industrial finishes and powder coating, while a hex code such as #007cb0 describes the same tone as a mix of red, green and blue light on a monitor. Think of this RAL to hex tool as a translator between a printed catalog and a web page.
A printed color chip and a lit pixel are built in completely different ways, so no single formula turns one into the other. Instead, the tool reads from a dataset that pairs every RAL number with the hex color designers have agreed represents it in a browser. That is why the answer arrives instantly, and why two reference sources sometimes disagree by a few units in a single channel.
Who Needs a Color Converter
- A web designer or developer who must reproduce a RAL-specified brand tone in a stylesheet or UI kit.
- A manufacturer whose machinery and hardware ship in a RAL finish and who needs matching product images.
- A painter or signage shop that receives a client's artwork and has to order the closest RAL shade.
- An architecture team that wants renderings to show the same wall and facade tones as the paint schedule.
How RAL to Hex Color Conversion Works
Every conversion follows the same three moves, whether you run them in the tool or by hand on paper. When you need to inspect the raw bits behind a batch of hex values, the hex to binary converter handles multiple lines at once for a quick batch conversion.
Step 1: Enter the RAL Classic Code
Type the four digits of the number, for example 5015, with or without the RAL prefix. The validation step rejects an empty field or a number that is not in the dataset and shows an error message instead of a wrong answer.
Step 2: Press the Convert Button
The tool finds your code in its table and pulls the stored triplet of red, green and blue values. It then writes each channel in base 16 and joins the three pairs behind a hash sign. The color preview fills with the result so you can check it by eye before you use it.
Step 3: Copy the Hex Value
Copy the result into your stylesheet, a Figma file or a spec sheet. Press the Clear button to reset the input, the preview and the result before you look up the next code.
Worked Example: Converting a RAL Color Code to Hex
Say a facade supplier lists RAL 5015, a sky blue, and your team needs it as a web color. The stored triplet for that finish is 0, 124, 176. Each channel is a number from 0 to 255, and base 16 needs exactly two digits per channel: Enter your hex number into the hex to base36 converter to get its compact Base36 equivalent, distinct from a byte-encoding scheme like Base64.
$$N = 16 \times d_1 + d_2$$For the green channel, \(124 = 7 \times 16 + 12\), and twelve is written C in base 16, so the pair is 7C. Blue gives \(176 = 11 \times 16 + 0\), which is B0. Red is zero, so it becomes 00.
| Channel | Decimal | Base 16 pair |
|---|---|---|
| Red | 0 | 00 |
| Green | 124 | 7C |
| Blue | 176 | B0 |
Join the pairs and you get #007cb0. The same color is HSL 198°, 100%, 35% and HSB 198°, 100%, 69%. The naive CMYK split of that triplet is 100, 30, 0 and 31, but a print shop will apply its own press profile, so treat CMYK from any digital tool as a starting point.
Reading the Extra Values Beside the Hex Code
The hex result is only one view of what the converter returns. The same triplet can be restated in other models, and each one is better at a particular job.
Hue, Saturation and Lightness
For 5015, the hue angle of 198° places it in the cyan-blue part of the wheel, saturation of 100% means no grey is mixed in, and lightness of 35% says it sits on the darker half. These numbers are handy when you need a lighter hover state or a muted background that stays in the same family: change only the lightness and keep the angle.
Ink Percentages
CMYK expresses the answer as ink coverage. A value of zero yellow and about one third black tells a printer the finish is a clean, deep blue rather than a greenish one. Ask your supplier for their own profile before you print anything critical.
Which Value Should You Store?
Keep the hex notation for code and the RAL number for procurement. Everything else can be derived on demand.
RAL Colour Chart of Common Shades with Hex Notation
The table below is a short RAL colour chart of widely specified finishes, each paired with its RGB triplet and hex notation. Treat the numbers as a guide: a sample on a display depends on display settings and ambient light, and the physical fan deck stays the final authority.
| RAL code | Color name | RGB | Hex value |
|---|---|---|---|
| RAL 2004 | Pure orange | 226, 83, 3 | #e25303 |
| RAL 5010 | Gentian blue | 0, 79, 124 | #004f7c |
| RAL 5015 | Sky blue | 0, 124, 176 | #007cb0 |
| RAL 6005 | Moss green | 17, 66, 50 | #114232 |
| RAL 6018 | Yellow green | 97, 153, 59 | #61993b |
| RAL 8017 | Chocolate brown | 68, 47, 41 | #442f29 |
| RAL 9005 | Jet black | 14, 14, 16 | #0e0e10 |
Names carry the character of each family: signal yellow and traffic red are loud, high-visibility tones, anthracite grey is a dark industrial neutral, ultramarine blue leans deep and saturated, and pure white is a warm off-white rather than paper white.
Turning a Van's Green into a Hex Color for a Button
A landscaping firm is putting its fleet livery on its booking page. The van invoice lists the body finish as RAL 6018, and the developer, Imran, has to give the "Book now" button the same green.
He types 6018 into the converter and presses Convert. The preview fills in a leafy green and the result reads #61993b, from a stored triplet of 97, 153, 59. He pastes it into the button's background rule and reloads the page.
Before shipping, he checks the white label on top. The relative luminance of that green gives a contrast ratio of 3.43:1 against white. WCAG 2.1 level AA asks for 4.5:1 on normal-size text, so the button misses by more than a full point even though it matches the van exactly.
| Finish | Hex notation | Contrast on white | AA for normal text |
|---|---|---|---|
| RAL 6018 | #61993b | 3.43:1 | Fails |
| RAL 6005 | #114232 | 11.36:1 | Passes |
Two options follow. Imran could enlarge the label to 24 px bold, where AA only requires 3:1, and keep the exact livery green. The brand owner prefers a smaller label, so he runs the lookup again with RAL 6005, which returns #114232 (17, 66, 50). That dark finish measures 11.36:1 against white, past AA and past the 7:1 bar for AAA.
He keeps 6018 for the button border and the large heading, where it matches the van, and uses 6005 for button text and body links. The brand sheet now records "livery green 6018 = #61993b, text green 6005 = #114232", so the next developer never has to guess which RAL number sits behind which value.
Reverse Lookup: Hex to RAL Matching
Going the other direction is harder, because a web color usually has no exact twin in a catalog of a couple of hundred finishes. A hex to RAL tool therefore finds the closest match by measuring how far your color sits from each catalog entry in RGB space.
The Euclidean Distance Formula
$$d = \sqrt{(R_1 - R_2)^2 + (G_1 - G_2)^2 + (B_1 - B_2)^2}$$Take a brand color of #0b78a8, which is 11, 120, 168. Its distance to RAL 5015 is \(\sqrt{11^2 + 4^2 + 8^2} = \sqrt{201} \approx 14.2\), the smallest in the table, so that is the suggested match.
| Candidate | Triplet | Distance |
|---|---|---|
| RAL 5015 | 0, 124, 176 | 14.2 |
| RAL 5010 | 0, 79, 124 | 61.1 |
| RAL 6005 | 17, 66, 50 | 129.9 |
A low distance means a close match, but it is not a promise of an identical finish. If the number is above roughly 25, adjust the source color and run the lookup again before you commit to a purchase order.
Choosing the Range to Search
A smaller range returns fewer, more familiar answers, while the wider RAL Design range offers finer steps and usually a smaller distance. Pick the range that your supplier can actually deliver, otherwise a better numerical match is worthless in practice.
RAL Color System vs Hex Color Space
The two notations answer different questions. RAL names a physical finish that you can hold, and the number refers to a printed chip. Hex describes light: each of the three channels runs from 0 to 255, which gives 256 × 256 × 256 = 16,777,216 possible colors in the sRGB color space.
- RAL Classic covers the best-known set of finishes used on buildings, vehicles and machinery.
- RAL Design is a larger system organised by hue, lightness and chroma for finer matching.
- Hex is simply base 16 shorthand for three channel values, convenient for CSS and design tools.
- CMYK describes ink on paper, so its values shift with every press and substrate.
Because the systems are separate, a digital color is only an approximation of a physical paint. Pantone and NCS add two more catalogs to the mix, and none of them maps one-to-one onto the others.
Limits of Digital Color Conversion
Three things keep any conversion from being perfect. Displays emit light while coatings reflect it, so a metallic or pearl finish has no honest hex equivalent. Gloss changes perceived lightness. And every device has its own gamut, which means the same hex string looks slightly different on a phone and on a calibrated desktop panel.
Practical Uses of a RAL Code in Digital Design
The most common job is carrying a real-world finish into a browser, from a product page to a UI mockup. Match the hero banner to the shop front, or keep an app accent in step with the housing of a device, and your pages feel like part of the same brand.
Brand Colors and Branding Guidelines
Many companies store both a RAL number and a hex notation in their brand guidelines. When a supplier changes, the pair keeps the printed brand colors and the web palette aligned without a new round of guesswork, and it protects branding consistency across packaging, signs and the site.
Web Design and Front-End Work
On the front end, the hex output becomes a custom property that every component inherits. Define it once, then derive hover and disabled variants from it rather than picking new tones by eye.
Product Interfaces and Graphics
A device maker can set a touchscreen interface in the same hue as the enclosure, and a studio producing packaging graphics can proof against the digital value before the physical run begins.
Supplier Documentation and Specification Sheets
Run each code from a supplier's technical file through the tool and compare the results against your approved palette. Any value that drifts stands out immediately, which is far quicker than comparing a fan deck to a display. Write the winning pair into the specification so painters, printers and developers all read the same line.
Getting an Accurate Hex Color Between Screen and Paint
A few habits keep surprises small. Calibrate your monitor before you judge a swatch, and view chips in daylight rather than under warm bulbs. Ask for a physical sample before approving a large order, because a coating's gloss level changes how light reads even when the code is identical.
- Use the same hex notation in every file, so the layout stays consistent across mockups and code.
- Record the RAL number beside the hex string in your style guide.
- Check contrast: a light tone such as yellow green falls under the accessibility minimum for text on white, while a dark one passes.
Common Hex Color Mistakes When Matching Finishes
Most bad matches come from a handful of repeatable slips rather than from the data itself.
Trusting One Source Blindly
Catalogs published by different vendors list slightly different triplets for the same number, since each one measured or approximated the finish on its own. If your project is strict about tolerance, pick one reference and use it everywhere, including in your brand sheet.
Ignoring Context and Surrounding Tones
The hex string the converter returns for a RAL number reads differently depending on its neighbours: #61993b looks lighter on a dark header than on white. Judge the result on the actual page background it will sit on, not on an empty canvas.
Rounding the Channels
Shortening a six-digit string to three digits changes the result whenever the pairs are not repeated. Keep all six characters so that the value you store is the value you looked up.
Troubleshooting Your RAL Code Lookup
If the result box stays empty, the cause is nearly always the input. Enter only digits, such as 6018, and avoid spaces or letters. A number that is not part of the supported RAL Classic range triggers the error message, and the Clear button wipes both the field and the preview so you can start again. For a finish outside the table, the reverse lookup above still finds the nearest neighbour.
Finally, remember that the tool is free and online, so there is nothing to install, and every lookup runs instantly in your browser.
