@ jmm1837....I think you are very courageous answering this exceedingly difficult question! The answer above is probably something like I would say. I've been an artist for many, many years but not famous, not well known although I've sold many works and can turn my hand to any style, my preference for my own interest is "in the style of Turner" I've written a book on Colour Mixing for artists which is a teaching text. I'd say that there are not many questions I cannot answer about Colour....with the exception of these kinds of questions....to which, in my opiion, I concur with you, there is no one answer. I often thank my lucky stars that I live in a 1900s timber home that resembles a log cabin inside....Queensland Hoop Pine VJ ceilings, walls and floors, silky oak arctic glass casements, Hoop Pine or Silky Oak doors...and the only colour is the furnishings...and I can't even decide on these! So - to ask me "What Colour" to paint the walls of a house for sale really jangles my brain! I've never had to resolve that dilemma here...I'm not going to paint it...ever! So how to assist in this dilemma? As you explained, jmm1837, older character home -use some colour, newer home with clean lines - light neutrals...so far I agree. BUT...I was watching one of those TV home reno shows...A couple who could not agree on any colour for anything and a designer ,( bless her persevering, understanding, patient, kind, and dog-with-a-bone determination) trying to help them do a reno. I was suddenly inspired ! I had encountered once a colour that contained all colours, that would 'go with' all colours but yet could be described as Lilac but wasn't...and Neutral but wasn't. Thinking "lilac" I think of demure, age appropriate attire and lace...so not very decorator inspiring. The particular LILAC they used for skirting boards, trim and door jams alike worked like magic! I can see readers screwing up their noses and almost hear others saying ERK...That was my reaction when the word Lilac was mentioned.... I did not take any notice what the brand was, I was too astounded by the finished effect. It wasn't Lilac, it wasn't grey...it was a colour but it was a neutral ....and it reflected a different shade depending on its position in the room and its proximity to soft furnishings. So....what's my solution? With both styles of home...think neutral with a tendency to the palest, palest of violetey greys maybe complemented with a drop of ochre ever so subtle...So a neutral to the eye but a colour depending on its position in the house, and keep it all the same, no accents...I believe the light and adjacent furnishings will work with such a hue. Colour is Magic. I'm convinced more than ever that it can morph into any hue. Just some thoughtful reflections from a colour fanatic.

Oh! Sorry I misunderstood your post. I think it depends on what type of planting you will have along your fence line. I assume it will be a Colorbond fence? I wouldn't introduce Shale grey. Of those two I'd prob stick with Surfmist but then I think greenery looks FABULOUS against Monument fencing. The whole back of my house is Surfmist acrylic render and we have chosen Monument fencing and garden retainer walls/seating around the perimeter of our garden as it provides a background of depth against greenery. I know you don't like Monument though. Houzz does give you a variety of opinions and does make you think outside the square. Good luck with your choice!

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

I agree with pottsy99's approach. I'd paint the concrete portions of the wall. Depends what the colour scheme of your garden is - charcoal might suit. Personally, I love off-white but it might not go. Whatever colour you go with, I'd also paint the terracotta pots to have more cohesion. At that point, you might consider leaving the stones alone (perhaps a tidy up if you're feeling energetic.) You could also go for weeping plants. Dichondra silver falls are my favourites. They are also relatively easy to propagate and grow. However, mine always die during the Perth summer heat. Heartleaf iceplant are also easy to grow, propagate and hardy but does attract snails.
