This is the simplest explainer ever on how my neutral colour wheel and large colour boards work together for the perfect colour selection everytime.

The Missing Visual That Connects My Neutral Wheel to the Large Colour Boards

If you’ve been following me for any amount of time, you already know this:
neutrals are the hardest colours to choose.

Not because the colours themselves are complicated — but because the differences between the viable ones are incredibly subtle. And subtle is exactly what the typical paint chip cannot reveal.

I’ve been teaching how to see neutral undertones for 17 years, and yet somehow, I have never shown you this image:

Front of the Understanding Undertones Neutral Wheel

This is the first time I’ve revealed the full relationship between my Neutral Colour Wheel and the curated universe of Large Painted Colour Boards behind it.

And honestly?
It’s the missing visual that makes the whole system click.

Back of the Understanding Undertones Neutral Wheel

And seeing them together instantly clarifies something I’ve been teaching all along:

The wheel and the boards aren’t random tools — they belong together.
You can use the wheel on its own for a small problem…
but the magic happens when you pair it with the collection of full-size boards.

You’re seeing 36 neutrals and whites from the complete curated collection of 50 above.

Why This Matters (Whether You’re a Homeowner or a Design Pro)

Let’s be very clear — if you are choosing:

• a kitchen cabinet colour
• a whole-home neutral
• trim and ceiling whites
• bathroom tile
• exterior stone or siding
• new furniture or hard finishes

… you’re not choosing from hundreds of random fan-deck colours.
You are choosing from a tiny, tightly curated set of useful neutrals and whites.

Once you determine that the countertop works with green beige (for example) you pull out the green beige samples from light to dark and simply choose (below).

That’s what the Killam Colour System has always given you.

But until now, I haven’t visually shown the powerful connection between:

The Wheel (the map)

and
The Large Boards (the actual terrain).

Here’s the simplest way to understand how this works.

When you’re decorating, the moodboard is where you gather the big ideas (below left) — the palette, the finishes, the feeling. Get my Moodboard course here, 3 modules, easy to digest, saving you hours of time.

But you would never finalize your selections based on the moodboard alone. The real decisions happen when the actual samples show up on site, in real scale, next to each other, in the real light, which is how you end up with the right colours for everything in the room (right).

It’s the very same relationship between my Neutral Colour Wheel and the Large Painted Colour Boards. The wheel organizes the concept — the categories, the undertone families, the direction. But the boards show you the real thing in context so you can make the right decision every single time.

The wheel organizes the entire system at a glance — 9 neutral undertone families on the front, each with three to five of the best light-to-dark corresponding paint colour options, and on the back, four gradations of whites paired with their corresponding system whites — so you can conceptually identify exactly what you’re looking at.

But the moment you need to compare a taupe to a green-grey or distinguish a pink beige from a green beige, the wheel alone simply can’t give you the clarity.

It’s not your fault.
The samples are just too small.
Any sample that size would be.

Which brings us to the entire reason the large boards exist.

Why You Actually Need the Large Boards to Make a Final Decision

It helps you identify:
“Is my Calacatta backsplash green grey? Is it blue grey? Is it green beige?” (It’s all 3 in this case)

What about the countertop I inherited? Is it taupe or violet grey? (Violet grey is what you’re looking at).

But here’s the reality:

Undertones are subtle.

Fan-deck–sized samples flatten the differences.
Only the large boards can reveal them clearly.

This is exactly why so many people buy the wheel and still feel unsure.
It’s not because they’re missing the “colour gene.”
It’s because the wheel is the map — not the terrain.

The differences are so refined — especially in the current trend of warm neutrals — that even trained designers get confused without a proper, full-scale comparison set.

Homeowners?
Forget it.
Cutting corners here is exactly how renovations go sideways.

When you have all 50 neutral boards in the system, from light to dark in every undertone category, the correct colour becomes obvious.
Not stressful.
Not mysterious.
Obvious.

This is the entire point of the collection.

And after you work with my large neutrals, you immediately discover how easy it is to sell any colour.

In each brand, I have two collections.

1. The Killam Colour System (BM or SW) – Neutrals & Whites, these are the 50 core system colours you need to choose a neutral or white for anything. They correspond directly to the neutrals and whites on the colour wheel.
2. The Colour Collection (BM or SW) – Additional colours including darks & saturated colours. A nice to have collection of amazing go to colours and darks.

Please note: we won’t be stocking The Colour Collections (2) any longer, we will just be focused on the system neutrals and whites (1). My Sherwin Williams Colour Collections are already sold out and we have 14 sets left in BM (at my last count) so get them now before they’re gone forever.

When the Wheel Is Enough

I want to be transparent:

There is one scenario where the wheel alone can solve your problem:

• You’re working on a small project
• You only need to identify the undertone you need for a minor selection like a returnable item
• You don’t need to commit to an entire neutral for a whole home or renovation

In that case, the wheel can help you narrow it down to:
“Okay, this is probably taupe… or maybe green grey.”

Then you can double-check the curated colours listed in my ebooks, and paint up those specific samples yourself.

Totally reasonable.

It’s just more powerful, especially if you’re embarking on a large project with several costly selections, to have the full collection of large samples to get crystal clear you have the right colour every time.

Bonus Alert: With any $50+ purchase, you’ll receive my Killam Colour System™ Digital Paint Dot Library—a $19 new digital tool that will make all your mood boards so much easier. It includes the full system of whites and neutrals in BM and SW.

And Yes — the Wheel Is Included With the Boards

Because while you technically can buy the wheel separately, the real power comes from having the full system.

The wheel helps you identify the undertone.
The boards confirm the exact, correct neutral within that family.

Together?
They eliminate the guesswork entirely, and that’s why I bundled them together from the beginning.

This is the time to invest in the system that keeps you from:
