Why material matching matters more than colour names
Paint doesn’t exist in isolation. It sits next to flooring, tiles, cabinets, and fabrics. If the undertones fight, the room feels slightly off even if the wall colour looks “nice.”
The Farrow & Ball look works because undertones are consistent across surfaces. This guide shows you how to pick paint that harmonises with what you already have.

Step 1: Identify the dominant undertone in your materials
The dominant undertone in your flooring or tile should drive your paint choice. Look for the subtle bias beneath the obvious colour.
Warm materials
Oak, walnut, terracotta, warm beige stone, brass. These want warm stone or pink-led neutrals.
Cool materials
Grey stone, slate, concrete, cool tiles, chrome. These want greige or cool-leaning neutrals.
If you’re unsure, use the undertone guide to classify your materials before choosing paint.
Step 2: Match paint undertone to the dominant material
Paint should echo the undertone of the biggest fixed material in the room. That material is your anchor.
| Material | Undertone direction | Paint family that works |
|---|---|---|
| Warm oak / walnut | Warm | Warm stone or pink-led neutrals |
| Cool grey tile | Cool | Greige or cool neutrals |
| Terracotta / clay | Warm | Warm stone, muted red-led neutrals |
| Blue-grey stone | Cool | Greige or green-led neutrals |
Once you choose the family, use the neutral palettes guide to build the rest of the scheme.
Step 3: Use trim white to bridge materials
If your materials are mixed (for example warm floors and cool countertops), a carefully chosen white can bridge the gap.
Use a white from the same undertone family as the dominant material, then choose wall colours that sit close to that white. The whites guide is the fastest way to get this right.
Step 4: Test paint with your actual materials
Don’t test paint alone. Put your sample boards next to the flooring, tile, or fabric. This is the only way to see if the undertones actually align.
Follow the sample testing guide and check in multiple lighting conditions. Material undertones reveal themselves most in low light.
Take quick photos in daylight and at night, not to choose the colour, but to spot clashes you might miss in the moment.
Step 5: Use finish to soften material contrast
If you have strong materials (dark timber, glossy tile), a softer wall finish can balance the room. Matt or eggshell reduces glare and makes the palette feel more cohesive.
Use the finish guide to choose the right sheen before painting.
Step 6: Use soft furnishings to bridge undertones
Rugs, curtains, and upholstery can act as an undertone buffer between paint and flooring. If your flooring is warm but your walls lean slightly cool, a rug with both warm and cool threads can help the transition feel natural.
This is especially useful in open-plan spaces where flooring flows through multiple zones. Use the open-plan guide to keep the palette consistent while soft furnishings do the heavy lifting.
Step 7: Know when to contrast on purpose
Sometimes contrast is the right move — but it should be intentional. If you want a crisp, modern look, a cooler wall against warm flooring can work, but only if the trim white bridges the gap and the finishes stay consistent.
If you’re unsure, stick to undertone harmony first. Contrast is a design choice, not a default.
Common material matching mistakes
- Ignoring undertones: The room feels conflicted.
- Choosing paint first: The flooring makes it look wrong.
- Too many undertone families: Visual noise.
- Testing paint alone: You miss the material clash.
- Overly bright whites: They exaggerate material differences.
These mistakes are why “perfect” colours suddenly feel wrong once furniture goes back in.
The reality check
Materials are permanent. Paint is flexible. Match paint to the materials you can’t change, then build the palette outward. That’s how you get a cohesive, expensive-looking space.
If the flooring wins every time, it’s usually an undertone mismatch.
