Colour-blind-what they see

[shootingstar]

My brother once attempted to install a car radio when we were in high school. He got the wires reversed and blew all electrical in the car! Boy do I have stories of him growing up.

Gee. The guy that I know, is a civil engineer. And since our dept. does handle engineering drawings, often these drawings have coloured markings..sometimes critical because they are hand marked with colour markers or Autocad lines, to show very recent design changes that must be implemented right there-- out in the muddy areas outside.

Wonder how he copes..or he's asking alot of questions from other folks ..if they are around and can interpret the engineering drawing on hand.
