Over the last 20 odd years I have used green, red and orange tractors, never blue because until lately, we never had a NH dealer close. Over that time, without doubt, the best tractor I have used is the 50 year old JD 820 we have at the farm. It just feels so solid and safe and it just keeps on running. The last 3 tractors we have bought have all been Kubotas but that has nothing to do with color, just specifications and price.
So, my advice would be to go find a tractor that you like with the options you want at the best price you can get and go with it, irrespective of color. I think that most modern, premium tractors are pretty much of a par. What sets one one above another is that some may offer features that another may not, and that you may not want anyway, or the pricing for that particular month may be very competitive. I have never owned or operated a NH but if their quality was as bad as some of the stories that get thrown around would suggest, they would have gone the way of dinosaur ... died out years ago. They're still here so, they can't be all that bad. Remember, any new piece of equipment can have faults or glitches, it's a fact of life.
