Thanks - some have a bit more grey shade in the red as well
I wouldn't call it a big difference, and I suspect that it won't show up on a football shirt or racing car.
But in a year or two, neither Manchester United nor Ferrari will be sponsored by Vodafone ....... McLaren will carry Vodafone sponsorship from 2007 (something wrong with Italian red being on a British car not a Ferrari I think we'd agree, if they dare do it)
