Who said you liked her for her looks?
We were all just saying you were way too pressed, and that might scare her off because no one (either gender) likes someone that comes on too strong. Also, regardless of why you like red, you should also consider the way she will interpret it, since you are so intent on making a good impression. A red rose represents LOVE, and every woman knows that. Its very common for other rose colors to be used for friendship, newly-daters, etc. Although we can give you all the advice we'd like, its solely up to you to take it.
