Here are the direct rules on the bumper text color rule:

2011: “<R09>...The numerals must be at least 4” high, at least in ¾” stroke width and in a contrasting color from its background...”
2012: “[R35] ...The numerals must be at least 4 in. high, at least ¾ in. in stroke width, and be either white in color or outlined in white...”

As the lead inspector at your event, I can tell you that unless the white part is 3/4" wide, if I had seen them they would not have passed. However, I was much too busy looking at other problems.

And I can pretty much guarantee you they will not pass at your next event.....

Back to the OP. Legality of anything in competition is decided by the GDC and the officials at any competition. Chief Delphi is not the best place to ask about rules or legality because most people who read these forums have no direct influence on the actual legality of something, we can only speculate and offer personal opinions about the rules.

If you have any doubts about something, I suggest that you search for a relevant Q&A or post one of your own. These will be much more reliable than anything that you see here.

Re: pic: illegal or not?
 

While true that legality is decided by the GDC, referees, and inspectors, that doesn't mean CD isn't the best alternative to inquire about legality. For one, the GDC has repeatedly stated that they will not offer any definitive ruling on the legality of the design; the format of their answers is consistent with this, as answers to a question often consist of the relevant rule(s) and nothing more, leaving the team in question to interpret the answer. For another, there are numerous inspectors (e.g. Wayne and Al) and referees (Gary) who can offer their own personal opinions on gray areas and how they would rule on such matters at a competition.

TL;DR: Q&A is certainly a good route to take, but depending on how gray the topic in question is, CD is certainly a good place to ask the question.

That being said, the OP should clarify his post and what exactly he's asking is legal or not.

Thanks for adding that.

Re: pic: illegal or not?
 

sorry for my very vague post. fear not out bumpers are legal. those were last years. :D as for my OP, this was intended to be used in elims (if we make it) as a bridge tipper and grabber. as for varying bumper heights go this was made so the top was at 10 inches and the bottom clamped on. the clamp is more so for security whereas the main section of this is used to ensure robots dont "tip" over the edge when pushed close to the edge. all in all this is mainly for extra help. kind of like 148's stinger (using them as a reference) just wanted to see what the CD community thought.
thanks for your replies

Re: pic: illegal or not?
 

Psh, that's nothing like 148's stinger - more like 1114's bridge manipulator. You might want to take a look at Waterloo elims; their balancing strategy was to hook onto their alliance robot's bumper and drag them up the bridge.

In that case, I agree with your finding, as G37 only prevents intruding into the opponent's frame perimeter. That being said, make sure that if you use this method, that whatever you're latching onto has enough structural strength to withstand this linkage.
