I am not a 'pink' person, I don't always choose to use it, I know some people have a problem with pink in scrap booking terms, but I am against stereotyping so I have been using pink to scrap with photographs of my boys.
By bolstering up the black and white you can tone it down.
By layering it you can also tone it down.
These patchwork inspired layouts are also using pink with a black and white photo and some more monochrome.
This one of Sergio has an acetate layer over the top that has been printed with grey lettering.
Just a few ideas of scrapping with pink in a more neutral way. TFLx
