How to Match Your Foundation Shade Across Different Brands

You finally found your perfect foundation. The shade is spot on, the formula works for your skin, and you do not have to think about it anymore. Then the brand reformulates. Or your go-to shade gets discontinued. Or you spot a foundation from another brand that you want to try, but you have no idea which shade to pick. Sound familiar?

Finding a foundation shade equivalent in a different brand should be straightforward, but it is not. Every brand uses its own naming system, its own shade range, and its own idea of what "medium" or "sand" or "buff" actually means. There is no universal standard, which means you are basically starting from scratch every time you switch.

Why shade names are useless for cross-brand matching

The shade called "Natural Beige" from one brand and "Natural Beige" from another could be completely different colours. One might run warmer, the other cooler. One might be a full shade lighter. The names are created by marketing teams, not colour scientists, and they are designed to sound appealing rather than to communicate precise colour information.

Even shade numbers are inconsistent. Brand A might use "25" for a light-medium shade with warm undertones. Brand B might use "25" for something entirely different. Without a shared reference point, comparing shade names or numbers between brands is unreliable at best.

Colour values are what actually matter

Behind every foundation shade is an actual colour. Not a name or a number, but a measurable set of values that define exactly what that colour looks like. Colour scientists use systems like CIELAB, which describes any colour using three coordinates: lightness, red-green balance, and yellow-blue balance. Two shades that look identical will have very similar LAB values, regardless of what brand made them or what they decided to call them.

When you compare foundation shades using their actual colour values instead of their names, cross-brand matching becomes much more reliable. A shade with a LAB reading close to your current favourite is far more likely to be a genuine match than one that happens to share a similar name.

The manual approach

If you want to do this yourself, the process looks something like this:

1. Swatch your current foundation on a white surface in natural daylight
2. Take a photo with consistent lighting and no flash
3. Do the same with the shade you are considering from the other brand
4. Compare them side by side on screen at the same brightness

This works in theory, but it is finicky. Slight differences in lighting, camera white balance, or even how thickly you swatch can throw off the comparison. And it requires you to already have both products in hand, which defeats the purpose if you are trying to avoid buying the wrong shade.

Using a foundation shade finder app

The much easier route is to use a foundation shade finder that has already done the colour measurement work. The Cosmetic Shades app has a database of 4000+ shades across 24+ brands, each with precise colour values. When you select your current shade, it instantly compares those values against every other shade in the database and ranks the closest matches by accuracy.

The result is a list of foundation shade equivalents from other brands, each with a percentage showing how close the match is. A 97% match in another brand is about as close as you will get outside of being literally the same product. Anything above 90% is usually close enough that the difference is invisible on skin.

Foundation shade comparison is not just about colour

Worth noting: even a perfect colour match does not guarantee the shade will look identical once applied. Foundation formulas vary. A matte formula will look different from a dewy one. A full-coverage product will appear more opaque than a sheer tint, even at the same shade. The undertone might match perfectly, but the finish changes how it reads on your face.

That said, getting the colour right is the hard part. Once you know the shade is correct, you can adjust for formula preferences separately. It is much easier to work with a colour match and adapt to a different texture than to guess the colour entirely and hope for the best.

Building a cross-brand shade profile

Once you find your shade in a few brands, you start to see a pattern. You might be a "light-medium warm" across the board, but the specific shade number varies every time. Keeping track of your matches across brands saves you from repeating the process. The Cosmetic Shades app lets you save shades to a collection, mark them as owned or wishlisted, and add notes. Over time you build up a personal shade profile that works like a reference card for every future purchase.

It also means that if a friend recommends a foundation from a brand you have never tried, you can look up your match in seconds instead of wondering which shade to order.

Concealer and lipstick work the same way

Everything we have covered here applies to concealer shade matching and lipstick as well. The same colour science that matches foundation shades across brands works for any product with defined colour values. If you know your concealer shade in one brand, a shade finder can show you the closest match in another. Same for lipstick shade finder results. The principle is identical: compare the actual colour, not the name.
