I'm an actress there doing a アナと雪の女王 play they have me a Choice of Elsa または Anna my BFF says Elsa because of my voice my other BFF says Anna cause I'm a brunette.

I don't want to rehash the good アドバイス the others have given, but I'd just like to add that if your ユーザー名 has Elsa in it, あなた must be a HUGE fan, so あなた should own the moment 😉 This is the perfect opportunity for あなた to emulate Her Icy Highness 🌀 ❄️ ⛄️ Best of luck, have fun and, if possible, please share some pics and recordings with us 💐

Well you'd play whom あなた want to, just check both's personality and background in detail and then listen to your heart.

I think the answer is obvious; Elsa.

あなた have the voice it takes to play her, and I'm going to assume the 芝居 skills. So unless あなた actually wanted to play Anna because she's your お気に入り character または something, why would something as simple as the color of your hair stop that? So what if you're a brunette; that's why we have wigs.

In the end the choice is yours of course, but if the only thing stopping あなた is the color of your hair then...

In my opinion pick the character あなた like もっと見る and think あなた can do better?

Go with Elsa.

It's showbiz, and in showbiz they've got wigs n' makeup. I'm pretty sure no one's going to audition and have platinum londe hair and a belty voice.
