Picking a roof colour is a big call. You will stare at it for years. If you are here, you are probably eyeing the monument colour, and fair enough. It is one of Australia’s most searched dark grey exterior colour choices. This guide shows what Colorbond Monument really looks like, what goes with it and how it acts on a Melbourne home. We also cover heat and repainting, so you can lock it in with zero regrets.
What colour is Monument?
Monument is a deep charcoal grey. It sits between soft black and true dark grey. Colorbond made it for steel roofs and fences, and Dulux sells a matching paint. People search “colorbond monument” and “monument colorbond”. Same colour, different word order. Dulux also sells it as a paint colour, so you can match steel with painted walls, doors and timber. Handy if your fence or garage is not Colorbond.
Quick snapshot:
- Tone: deep charcoal grey
- Undertone: neutral, a touch cool
- Finish: matte to low sheen
- Best for: roofs, fences, gutters, garage doors
- Vibe: modern, calm, high contrast
Is it black or grey?
It is grey. It just reads black in low light. In daylight you will see a soft grey lift, especially next to true black. Night Sky is the one that goes near black. Monument is the safer pick if you want dark without the harsh look.
Why it sometimes looks blue
Dark greys pick up whatever is around them. Under a clear Melbourne sky, Monument can look slightly blue. Cool morning light and overcast days do the same thing. In warm afternoon sun it swings back to neutral. So always check a sample outside, at different times of day.
Monument vs Woodland Grey vs Basalt
These three get mixed up a lot. Here is the quick difference.
| Colour | Depth | Undertone | Vibe |
| Basalt | Darkest of the three | Neutral, slightly cool | Bold and modern |
| Cool grey (Note) | Dark, a bit softer | Cool grey | Sleek, less stark |
| Woodland Grey | Mid tone | Warm and earthy | Relaxed and natural |
Rule of thumb: Monument for contrast, Basalt for softer, Woodland Grey for natural.
So, is Monument darker than Woodland Grey? Yes, by a fair bit.Woodland Grey suits leafy streets and bush blocks. People who search “woodland grey colorbond” often want something softer than Monument. Basalt colorbond sits in the middle. When in doubt, hold all three next to each other in real light, in both sun and shade. Want the whole lineup? Check the full Colorbond colour range.
Where Monument works best
Roofs
This is where Monument shines. It hides dust and bird marks better than pale roofs, looks sharp and suits modern, Hamptons and heritage homes. The trade-off is heat, and we cover that below. Got a faded roof? Our roof painting service can bring it back to a clean, even finish.
Fences and gates
A dark fence makes plants pop and hides scuffs. Use proper fence paint on timber, or go with steel panels. Either way, pick an exterior paint made for that material. Interior paint will peel fast outside. Timber fences also soak up paint, so budget for two coats. Steel panels need much less upkeep than timber.
Gutters, fascia and window frames
Monument gutters and fascia give a crisp outline against light walls. Window frames look sharp. Tip: match the gutters to the roof so the lines flow. Some people go Surfmist gutters against a Monument roof. It looks fresh, but it shows dirt faster.
Render and weatherboard
Full Monument acrylic render can feel heavy. It also shows chalking and hairline cracks more, and it gets hot in summer. Try it on a feature wall or garage instead. On weatherboard, it looks moody and modern. Thinking about it? Read our guide painting a weatherboard house.
What goes with Monument
Trim and accent colours
Light colours pop against dark Monument. Our go-tos:
- Surfmist: soft, clean, low drama.
- Natural White Dulux: a warm white that suits trim and doors.
- Shale Grey: a light warm grey for eaves and gutters.
- Dulux Dieskau: a warm, earthy pick in the taupe colour family.
Keep it to three colours. More gets messy.
Brick and render pairings
- White render: crisp, classic, always works.
- Red brick: Monument calms the warmth down.
- Cream brick: add warm white trim.
- Timber accents: warm doors and pergolas look great against Monument.
- Grey colour walls: keep them lighter than the roof, or the house feels flat.

Monument on a Melbourne home
How light and aspect change it
Melbourne light is moody. North-facing roofs get full sun, so Monument looks warmer and fades faster. South-facing roofs sit in shade, so it looks darker and cooler. Trees, fences and cloud shift it too. Always sample on your actual roof.
Heat absorption on a dark roof
Dark colours soak up heat. Monument has a low LRV (light reflectance value), so it bounces back very little light. On a hot Victorian day, your roof space will cop it. Fixes that work:
- Good insulation
- Roof ventilation
- Sarking under the sheets
- A lighter roof colour like Surfmist or Shale Grey
It is not a dealbreaker. Plenty of Melbourne homes wear a dark roof and stay comfy with decent insulation.
Painting Colorbond Monument as a repaint
Prep, primer and product
Prep decides everything, and paint only sticks to clean, prepped metal. Here is the order:
- Pressure wash to lift dirt and mould.
- Scrape loose paint and treat rust.
- Prime with a metal primer.
- Roll on two coats of roof-grade acrylic.
Steep roofs are risky, so leave them to a crew. Curious about what roof painting costs? Our price guide breaks it down.
Colour matching an existing Colorbond finish
Old roofs fade. Sun can soften Monument to a lighter grey over the years. Dulux sells a matched Monument, and we test a patch first. If your fence and fascia are older, we match to what is on the house today, not the fresh tin. That way it all looks like one set. Pro tip: paint a small patch on the roof edge and check it after a few days.
