Thinking of using Dulux Powdered Rock for your exterior colour selection? You’re in the right place. In this post, I’ll walk you through two timeless exterior colour schemes I’ve created that pair beautifully with this popular Dulux colour.

As a qualified interior designer and colour expert, I’ll show you exactly how to use this colour, what undertones it works with, and how to create a cohesive exterior scheme—even without hiring a designer.

🎨 About Dulux Powdered Rock

• LRV (Light Reflectance Value): 51

• Undertone: Grey with a soft green undertone

• Type: Mid-depth exterior colour

Although it looks like a deep mid-grey, remember that exterior colours appear 2–3 shades lighter outdoors due to natural light. That’s why understanding undertones is key to making it work!

🏡 Exterior Colour Scheme 1 – With White Windows

This scheme is perfect for weatherboard homes or Hebel/rendered façades with white trims.

Main Render Colour: Dulux Powdered Rock
Window Frames: White (pure white for contrast)
Fascia, Gutters, Downpipes: Colorbond in a soft warm grey-green (works perfectly with the undertone of Powdered Rock)
Garage Door & Front Door: Same as fascia/gutter for a cohesive finish
Window Trims/Mouldings: Use the same white as your windows for a clean, sharp outline
Optional Feature Column or Balcony Accent: Choose a slightly darker grey-green to add depth without introducing a new undertone

💡 Why it works: This entire scheme stays within one undertone family—grey with a green base—which creates harmony, contrast, and timeless elegance.

🏠 Exterior Colour Scheme 2 – With Black Windows

Looking for something bolder and more modern? This scheme features black window frames for a striking contrast.

Main Render Colour: Dulux Powdered Rock
Window Frames: Black (adds instant sophistication)
Roof: Dark grey or Colorbond Monument
Fascia & Downpipes: A grey-green tone that ties into Powdered Rock
Garage Door & Front Door: Match fascia and downpipes for a cohesive finish
Optional Feature Balcony or Column: Add a deeper version of the same undertone for layered interest

💡 Why it works: Black adds contrast and edge, while staying true to the neutral colour palette. A great choice for modern homes with strong architectural lines.

⚠️ Don’t Forget These Key Exterior Elements

While render and trims are important, don’t overlook:

• Exterior tiles or stone

• Driveway or front concrete paths

• Fencing colours

• Garage and front door textures

• Roof colour coordination

These elements all need to match your undertone—in this case, grey-green—to keep the scheme balanced and beautiful.
