Subject: colour contrast in signs

I am attempting to quantify standards for signage on this campus with 
respect to the requirement that colours be chosen so that characters 
contrast clearly with the background.
A figure that has been suggested to me as a standard is a 
difference in reflectivity rating of 70% between characters and 
background.
Can anyone confirm this or any other standard you are aware of?

Many thanks
