why yellow there is plenty of other colours that can have print easily read on them

Yellow is a nice bright bold colour and black writing on yellow background has the highest contrast of any combination of colours....that's why it is always used for airport signage.

same reason that dusters are yellow;
answer= 'Why not yellow it's a nice color and noticeable.' Plus if they weren't yellow [pages] all the adverts would fail; What colour did u want?

This is not meant to sound sarcastic, but if they were green, someone would ask "why green"?
