Reducing orangeness of bricks

[fiorentina]

Our neighbours are having an extension with a parapet roof attached to the rear of our property so rises above our ground floor roofline - is visible through our skylights. The bricks they have used are very bright orange and don’t look nice or match the house bricks in anyway - they are 1900s properties. Does anyone have any recommendations please for what we can do outside to tone them down? To age terracotta plant pots I’ve used yogurt but not wanting to turn the bricks green, or damage them obviously.
Thanks

Have they complied with planning rules? Often bricks are meant to be matching for what’s there already.

I don’t think you can touch your neighbour’s bricks :/ unless a party wall and it’s your side.

You could put window film on your skylights to tone it down?

Thank you, it’s a party wall and is our side, don’t worry - I wouldn’t touch their side!
I will re-read the planning permission, that’s a good point. I guess how strict they are on ‘matching’, maybe they are the same colour as when our house was built but just don’t have 100 years of weathering!

Resist any temptation to paint them. You will have to repaint regularly, and even if you do they will look $%!7 for half the intervening time.

First, check for planning permission and party wall agreement. They may not have needed either, but they are in trouble if they did and proceeded without or didn't follow the requirements. Find out what rights you have. Then try and reach an agreement with them as good relations could be important in future.

Bricks can be dyed. Even just changing the mortar (by repointing or dying it) can make a surprisingly dramatic difference. These are specialist jobs, and a brick tinting professional would be needed.

We had a similar problem and someone suggested painting it with yoghurt, so the enzymes would speed up the weathering process. I didn't try it...
