The One Rule for Mixing Wood

Can I mix different woods in the same space?

The answer is absolutely yes.

In fact, using different woods can make an interior feel much more layered and natural.

The trick isn't matching the exact colour — it's understanding the undertone.

Can you spot the difference between the woods in the image above ?

If you can't, here's the easiest way to understand why some wood tones work beautifully together while others simply don't.

The secret isn't matching the exact colour. It's understanding the undertone.

Warm, Neutral or Cool?

Just like paint colours, wood has an undertone.

Warm woods lean towards yellow, orange and red. Mahogany and cherry are obvious examples, while many oak finishes can also become quite warm.

Cool woods are more muted, often carrying grey, taupe or subtle olive undertones. Ash, certain white oak finishes and some walnuts can fall into this family.

And somewhere in between are

Neutral woods — balanced finishes where neither warm nor cool undertones dominate. These are particularly easy to combine and can act as a bridge between other wood tones in a space.

Natural wood isn't literally “cool” or blue. We're simply looking at the subtle undertone beneath the overall colour.

Save the guide below for your next furniture or material shopping session. 

Instead of trying to find exactly the same wood colour, use it to identify whether the samples you're looking at belong to the warm, neutral or cool family.

The easiest rule to remember?

Match the undertone, not the shade.

Cool woods have soft grey or beige undertones. Think White Oak or Ash.

• 

Warm woods have richer golden, brown or reddish undertones like Walnut Cherry or Mahogany.

• 

For example, all these wood tones are cool. One is light, one is medium and the last is dark.

The same goes for warm woods. No matter the depth of the color they all share the same undertone. You can mix different shades, as long as they stay in the same family.

Now, Let's Level Up: Look at the Grain

Once you've understood colour, there's another layer to consider: the wood grain.

For a modern, minimal interior, look for cleaner, quieter and more uniform grain patterns.

For a rustic, traditional or more collected interior, stronger grain, knots, ageing and natural character can work beautifully.

Think about grain almost like pattern —

not every wood surface needs to compete for attention.

One expressive wood can take the lead while the others remain quieter.

The Takeaway

Mixing wood tones doesn't mean finding a perfect match. It's about creating a visual relationship between them.

Start with the undertone, then consider the grain and finish. Once those elements speak the same language, you have much more freedom to play with light and dark, old and new, subtle and expressive.

The goal isn't for your woods to match. It's for them to belong together.
