Are there any wet utility estimators here?

I have a question for seasoned utility estimators. When you do your takeoffs do you use all the same color for each utility such as storm, water and sanitary? For instance, storm is all green, water is all blue, sanitary is all orange? I have been using different colors for each different type of pipe and/or structure and it doesn’t matter if it’s storm, water or sanitary. My buddy says it should all match APWA colors so all storm should be green, etc. I understand but find it difficult to distinguish between pipe types, etc.
