Whisper white is so very barely warm, I think it would achieve what you are after as it is often used in cool colour schemes. You can view the full range of Dulux whites on the attached link. If you click on a colour it will give you the break down of red, green, blue content for each colour. Just remember the colours on the screen will look different on your walls as the computer uses subtractive colour and you'll be painting with additive colour. http://www.dulux.com.au/specifier/colour/colour-atlas

Hey Dounia The colour and the way it has been painted is very much what we saw in the late 90's and early 2000's when we all went through the textured paint feature wall craze. But, saying that Paint and design technology have come a long way since then and I would encourage you not to give up on the copper idea and use a modern approach and product. Dulux have recently added their new range of Design Effects, Here's the copper and concrete look. There's also other options available at www.dulux.com.au. You can email them for a copy of their brochure or they are readily available at Bunnings in the paint section. Thanks Paul

Try dulux snowy mountains. Just hope you plan to bring some colour and textured elements into space. With the tiled light floor, the effect might a bit cold.

I would not paint that wall. Instead I would install a rectangle huge colourful painting. This will bring interest and texture to the whole room. If you are thinking of going grey, then would it be a feature? Would anyone notice? Your home is quite subdued in the colouring....maybe some colour may pop on that wall instead of more subtle tones.
