I was initially going to say a steel blue or similar , but I suspect the windspray is your roof colour ? If its not too late , why not go a windspray render , and steel blue roof -- knowing nothing else about you , your house or region , it sounds better to me .

I'll explain I hate anything boring , sorry I mean grey . So me personally i wouldn't do anything anywhere near grey as a render . Maybe , just maybe , do a light blue render ( sea-mist or maybe slightly bluer ) , but I'd just go a nice mid offwhite probably . As long as you don't have real red soil or bad waterstaining , it will look smartish and neutral and go with most gardens , fences , garage doors ,etc . Won't excite , but won't offend either .

Something a bit more controversial , would be a light mint tone , a light 50's blue , maybe even an apricot tone , but as you are ( presumably ) going a grey roof ( no matter what name someone wants to give it , it is grey ) , I am going to take a wild guess that you won't go with those tones . . . . . . . . . .

Those options are certainly not boring! The colour scheme is for a fence and pergola that dominates the backyard. Some parts will remain seen even once the garden grows. The windspray colour is inset as aluminium slats in the rendered fence. The pergola flooring is more warm - terracotta and beige. So there is a definite contrast making it hard to find a colour that makes it all work together. They are all inherited from previous owner. I’m after a relaxed/earthy vibe. So apricot is probably closest!

What colours are the house ?A photo would be good , but even a description , such as roof in . . . . . . , gutters . . . . . . . , brick or timber or render . . . . . . . . , basement . . . . . . . . . would be handy .

The other thing would be can you spray paint the aluminium slats -- to me , it depends on your house colours , but just on the above info , if you did the render in Windspray or similar , and then a steel blue or even monument spray on the slats , it would look smart with the beige and terracota , BUT if it didn't work with the house ,its pointless IMO .

House is also render, dulux natural white with terracotta tile roof. There is some monument painted wood along the top of the pergola.

I don't want to be rude , but surely if the house is Natural white render , and terracota roof , and the pergola is terracota floor and monument timber , you'd almost have to do the rendered wall in Natural White ?

That would be my pick ( without seeing photos ) , and I'd probably consider doing the house gutters in Monument -- I know the pergola is ancillary , but you want them to at least sort of match , plus Natural White , Terracota and a touch of Monument sounds pleasant .

A slight apricot tinge may also work , as you said , but I suspect it wouldn't work as well as matching the house tones . Maybe get a couple of pieces of heavy cardboard or timber and a couple of test pots and stand back with fresh eyes ?

Yes, natural white would be the logical choice. But it makes the windspray colour really stand out, which looks wrong given the other colours. And the white render on the fence gets very dirty and dusty. So after a colour that doesn’t show the dirt as much. Thanks for all the suggestions.

Again , without seeing the make-up of everything , maybe going a terracota render will reference the roof , although the windspray probably won't really work then . As per above , is it worth considering painting the ali panels , or even something like doing some 'window boxes' under those panels , and doing creepers and/or conifers and/or flaxes , in fact just about anything that partially hides the panels ?

Another thought too , again without knowing sizes or locations or anything too much -- with the windspray panels , if you got some laser cut panels , either get an engineer to make in your design , or off-the-shelf if the sizes line up , you could mount them maybe 100mm in front of these windspray panels , but have them in say a matt black or monument , or Corten ( that rusty steel ) . That gets another colour there , partially hides what I feel is an awkward colour , adds something trendy , a 3D effect , and some interesting shadows .

Not often I agree with Pottsy’s colour suggestions but Natural White is the obvious choice. The reason windspray sticks out is because it’s the wrong choice to start with - it doesn’t work with terracotta roof and the similar tones underfoot. So it’s either Natural White Or Monument with lots of garden and climbing plants (which would be quite lovely).

Wave you thought of painting the wind spray inserts, change it to something suitable
