I recall that several years ago there was a survey done by Autodesk and/or Toll Brother's regarding the use of color for lines in AutoCad with a black background. It entailed information regarding how the brain processes the line colors and which best to use per a psychologist. I have not been able to find it.

Can anyone point me in the right direction or to something similar. I am having a really hard time with a few people in my firm understanding the direction I am going with the line weight and color.

Thanks
