Looking for a warm grey paint that works both inside and outside your home? Dulux Grey Pebble might just be the perfect colour for your renovation or new build. In this post, I’ll walk you through its undertone, LRV, where it works best, what whites to pair it with, and how it behaves in different lighting and orientations.

I'm Bozica, a qualified interior designer and colour specialist. I’ve helped thousands of Australians create stunning, cohesive colour schemes that actually work with their space. Let’s dive in.

🎨 What is Dulux Grey Pebble?

• Undertone: Grey with a violet undertone

• LRV (Light Reflectance Value): 63

• Category: Mid-depth neutral grey

Grey Pebble is a sophisticated neutral that brings warmth and depth to any space. With an LRV of 63, it’s light enough to use in full rooms—but not deep enough for dramatic feature walls. It creates an elegant backdrop in modern, transitional, or classic homes.

🧱 Where Can You Use Grey Pebble?

Grey Pebble is incredibly versatile. Here’s where it shines:

Interior spaces:

• Open-plan living areas with plenty of natural light

• Bedrooms

• Entryways

• Theatres or media rooms

• Bathrooms or laundries (if your tiles or stone have similar undertones)

• Powder rooms

Exterior spaces:

• Weatherboard or rendered façades

• With white windows for a clean, timeless look

• With black windows for contrast and depth

• Paired with bricks or stone that have a violet or grey-violet undertone

⚠️ Avoid using Grey Pebble as a feature wall—it doesn’t have enough depth for contrast. For that, go for colours with an LRV under 40.

🧪 How to Test This Colour Correctly

Most people test colour the wrong way—on small swatches or on the floor! Here’s how to do it properly:

• Use A4-sized painted samples

• Always test vertically on the wall

• Place the sample against a white background (like Dulux Vivid White) to reveal the undertone

• Move it around the house and view it in different lighting throughout the day

☀️ How Grey Pebble Behaves in Different Light

Because of its violet undertone, Grey Pebble changes with the light. Here's how:

• North-facing rooms: Appears soft, warm and balanced

• South-facing or dark rooms: The violet tone becomes stronger and can look moodier

• East-facing rooms: Light and fresh in the morning, softens later in the day

• West-facing rooms: Rich and warm in the afternoon sun

💡 In darker or cooler rooms, you may need to add artificial lighting to reduce the violet appearance.

✅ Best White Paints to Pair with Grey Pebble

The right white paint can elevate your whole scheme. Here are the top picks:

1. Dulux Vivid White (Pure White)

The perfect crisp white with no undertone—great for skirtings, architraves, ceilings, and doors. It balances and softens the violet base beautifully.

2. Dulux White on White

Has a slight blue undertone, and works surprisingly well with Grey Pebble, especially in cooler, modern schemes.

3. Dulux Lexicon Quarter

Also blue-based, this soft white pairs nicely with Grey Pebble while adding a fresh, modern edge.

❌ Avoid soft or creamy whites—they will clash with the violet undertone.

🎯 What Colours Pair Well With Grey Pebble?

This colour is very flexible and plays well with other undertones when used correctly. You can combine it with:

• Deeper greys with a violet undertone (e.g., Dulux Grey Destiny)

• Taupes or mauves for added elegance

• Crisp whites for contrast

For exteriors, you can create a two-tone render using another grey-violet colour. It adds depth and interest without breaking the tone harmony.

🧱 Exterior Styling Tips

• Use white windows, fascia, and garage doors for a timeless look

• Match downpipes as closely as possible to the wall colour—downpipes are not a feature!

• Stick to the same undertone family when choosing tiles, concrete, or external finishes
