Side Car, or Blue Fleet?

I guess Side car is one of the old classic cocktails that became a base for many.

It was a classic, and worked well on me. Nice fragrance of brandy with good sour lemon juice.
Frankly, can't find very much of the difference between blue and white curacao, thus I'll post the thing called blue fleet together.

Seems like the only difference there is the color of the curacao.

White/Blue Curacao 1
Brandy 1
Lemon Juice 1
-> Shake
