As long as the home colour is red (either all red or predominantly so) I don't give a big rats arse if there are stripes in it or not. If it changed to blue then I would get the hump, but since that is not the case - not bothered.
PS I never wear (or buy) replica shirts anyway. I think they look stupid - especially on middle-aged pot bellied blokes wearing shell suit trousers and trainers.
