Wire pulls & Sub Floor work

Part of the negotiation with our electrician is that we would help with wire pulls, mud rings, and trim out on our job. So, this past few days we have spent helping with the first 2 things. As an electrical apprentice here's what I learned:
1) How to use Fish tape: A piece of round flexible metal wire that has a loop hole on both ends. You push the tape through the conduit and connect the wires to end, you can then pull the wire through the conduit so easily (vs trying to push it up through the conduit)
2) Wire pulling lubricant: I call it Butter. This is another fantastic trick to make the wires go through the conduit. We didn't use it very much, mostly on the longer runs.
3) White=neutral wire
4) Orange, Yellow Or Blue=hot wires used for ceiling lights/fans
5) Red or Black=hot wires used for outlets
6) Brown=wires used to make 3-4 way switches
6) Green=wires used for grounding-used for the bath fans

The other project this weekend was the 2nd layer of subfloor Here's a picture of my "crew".
