one of the reasons for that was That I was your Robot inspector at championship. i know its no big deal what color your wires are as long as you diferinate between + and -.

Having been a robot inspector. i've seen how the typical voulinteer inspector is generaly given an idea about how to inspect robots and then tries to go through the list to the best off their ability. and they tend to ruin a teams day when they don't pass you for somthing silly like that

However, the use of these colors is not very common in FIRST, so you should be prepared to show your inspector the rule in case he/she has not seen this before.

Yes your absolutely right be ready with the rule in your hand.
Im not saying that inspectors should "give you grief" . im saying that you will have some that will

On the topic of different colored electronics, why does FIRST give us the wrong color Anderson Connectors for our mainbattery plugs? Red signals 24v. Yellow is for 12v. Anyone happen to know?

It's a donation. It pretty much means we get what they are willing to give.

Do you know which standard that comes from, because I'm not aware of any such convention? Anderson makes both red and yellow SB50 connectors designed for 6 AWG and rated for 600 V (for insulation purposes). Their datasheet doesn't suggest a colour code.

I was thinking the same thing. I couldn't find a list on the Anderson site, but there was a list here http://en.wikipedia.org/wiki/DC_connector that suggests that at least Anderson has their own color coding recommendations.
