Disguising new brickwork - How to "age" new sections of build?

[DIY Dave]

Have added a new secion of brickwalling on to an existing patio retaining wall. The original wall is old - c. 1940's?, & the new brick work texture is a good match, but the colour is too "red".
Anyone know of any methods of surface "darkening" new bricks & mortar - and new patio flags for that matter?

Thanks for any help n advice

I've never done it but an old customer of mine once said that he used mushroom compost soaked in water for a few days and then painted on. Encourages growth of the lichens, algae, etc. which provide the aged appearance.

I was horrified at the thought of making my new paving grubby, but there's no accounting for taste...

We used watered down cow s**t on some new clay peg tiles to match in once - did sort of work....

Manure, tea bags, yoghurt (proper yoghurt, not the expensive stuff with all sorts of digestive aids added), sour milk, nettle water - all mixed with a bit of peat, compost or loamy soil and daubed onto the wall.

we have used green sheep s**t mixed with soot,then applied like paint,i was told by an old brickie that the acid in the s**t reacts with the soot and darkens the colour.
but in this scenario its normally just as well to put a climber or trailer against the wall
