Why the samples do not match the floor: shade variation explained

The rating exists because wood is not printed

Two planks from the same tree differ. Manufacturers deal with this by rating how much variation a given product is designed to show, on a four-point scale usually written CV1 to CV4 — or sometimes V1 to V4. CV1 is the most uniform; CV4 shows dramatic plank-to-plank differences in colour, grain and mineral streaking.

The rating is not a quality measure. A CV4 floor is not worse than a CV1 floor; it is a different look, chosen deliberately. What the rating tells you is how much the finished floor will differ from any one plank of it.

That is why it matters at the point of buying. Most disappointment with a wood floor is not a defect — it is a CV3 floor bought on the strength of a single CV1-sized sample.

What each rating means in a room

Oakline publishes this rating on the product page wherever the manufacturer supplies it.

CV1 — Uniform

Planks closely match one another. A single sample is a fair representation of the finished floor.

CV2 — Moderate

Visible variation within a tight range. 1 Oakline floor carries this rating.

CV3 — High

Planks differ noticeably by design. Judge it from several planks laid together, never one. 9 Oakline floors carry this rating.

CV4 — Dramatic

The widest range the scale describes. Expect strong contrast across the floor as an intended feature.

How to judge a high-variation floor before you commit

For anything rated CV3 or above, one plank will mislead you. Ask for several, set them next to each other on the actual floor of the actual room, and look at them in daylight and under the lamps you use at night — variation reads very differently under warm artificial light.

It is also worth looking at the product photography as a whole floor rather than as a swatch. Oakline’s product pages show the laid floor for this reason, not a cropped single plank.

Two related specs worth reading at the same time

Shade variation is one of three fields that together describe how a wood floor will actually look, and the other two are easy to overlook.

Surface texture describes what the plank feels and reads like — wirebrushed pulls out grain and hides scuffs, smooth shows them, scraped adds visible relief. Oakline’s engineered hardwood covers heavy scraped (8), subtle scraped (1) and smooth (1).

Edge profile describes how planks meet. A bevel cuts a visible groove at each edge and makes individual planks read as separate boards; a micro bevel does the same thing subtly; pillowed rounds the edge softly. Oakline’s range includes all three — pillowed on 8 floors, bevel on 1, micro bevel on 1.
