Re: red
You've got sooo many different shades of red to choose from. You've got blood red, maroonish red, deep red, the lists goes on.....Consider them all if you're not wanting to displease your relies. I'm sure there will be a shade of red that you'll like.
My preference for my big day insha'allah will be a deep wine/maroon....and a bright red for my nikah similiar to the one I've recently posted in bridal pics! Now just need to find a husband....
Anyway, if all else fails, and if you still dont want to go for red, then go for a colour you want and try to make them understand.
Good luck and do let us know what you decide!
