it's probably a custom colour tinted to match some other detail in the room but take some photos to your local paint specialist like Inspiration Paints and they should be able to help you get close..it doesn't look like the modern Parliament House in Canberra..the photo i found looks more like an older building like Kirribilli House or similar and looks more like a terracotta than copper which i would see with a greener tone so check out Federation Colours but even if you find the exact colour it will look different in different rooms depending on lighting, ceiling height and other features like artwork and furniture..but i wonder if the national library can direct you to historical records that retain the specific details...can't hurt to ask their advice...good luck with your search it is a gorgeous colour..

Thank you oklouise. Good suggestions there. Yes I think you’d be right in that it’s probably a custom tint. I’ll set up my own tinting lab in my garage and have a play.

One thing to remember about colours like this. That colour works so nicely there because of the 10ft plus ceilings and all the dark wood and low light in the room. Dark wood furniture and trims swallow colour, low lighting also makes it look warm rather than garish. Paint a similar tone in a well lit room of modern proportions and it's not going to have a similar effect.

Rather than trying to match a colour made for a particular room, try and get a similar feel in the room you have. Traditional, high ceiling rooms can take a far more dramatic colour than a modern room can. The scale and detailing make strong colour work in that kind of space.

The taubmans red which I think is closest is....Rum Punch.

Both have very similar orange hue, similar depth of hue.

In the oranges [taubmans] I would pick Cappricio or Orange Flash.

In the browns I would pick Fragrant Cloves.

The only problem with the colours you have tried is the hue isn't saturated enough. It's tempting to pick a lighter shade of the same tone thinking it will look darker on the wall but that isn't always true. I've painted what I thought were extremely saturated colours on furniture and walls only to discover it wasn't saturated enough.

I've just used the paint visualiser with a traditional and dark room and Capriccio seems to come the closest the effect you want out of all those colours. It seems to have that orangey earthy hue with a warm glow you are looking for. For a slightly more vivid colour in near identical range you could also try Orange Vermillion but is just a tiny tweak more saturated.

Thank you - that’s really helpful.

You’re exactly right about the saturation of the ones I’ve tried so far.
