If you cannot distinguish one driver from another, you are an idiot ... (hint: T-cam color).
You need to calm that down a little bit. The T-cam is much less recognisable (which of 12 drivers is it all with the same coloured T? You need to consider more than one thing), and changes every single year. In general, it's much harder to remember "in 2013 hamilton has a yellow T" (I actually don't know), than it is to remember, "Hamilton's helmet is dark yellow with blue/green/black stripes on the side".
Your statement is a bit like saying "if you can't tell Sean Connery apart from George Cluny because Sean connery is wearing a tweed jacket, you're an idiot". It's probably true that you should be able to tell via that, but it's a lot less convenient than simply going "he looks like Sean Connery, he must be Sean Connery".
