Is a bright blue winter jacket something that a teenager like me would wear?

I am a 13 year old guy. I just outgrew my old navy jacket, and needed a new one. I told my mum I prefer having dark colours, but she didn't listen to me and instead bought me a bright blue&white jacket. Whenever I wear this jacket to school everyone laughs at me calling me a baby, or a girl. I kept fighting with my mum & dad to get me a jacket with my colour choice, but instead told me I was stupid and that youths (even teenagers) wear bright colours. I can understand if it meant bright grey and plain white, but a bright blue? Isn't that a baby's colour? What should I do? How can I convince them to get me a colour which doesn't go too far? I asked them to see jackets made by Ecko, Nike, Adidas, and Puma and all the normal brands which I like, but they started talking junk saying I think like a gangster. I really need help and would be happy if someone could help me out here. Thanks. (btw I live in London, so I need to know of any stores within London which sell good jackets)
