Don’t get white, they get really dirty and turn brown. It would actually be pretty funny to get all white and then one green, so it looks like you got something stuck in your teeth.
You’ll get over the excitement and it’ll fade into boredom. Colors stop mattering after a few months. After a few years you just want them gone. I’ve had them. For 4 years.
Hot pink looks swell though. Black looks bad as it makes your teeth look less white.
Good luck man, I had mine for over 5 years and my teeth hurt so bad when they took them off that my retainer wouldn’t stay in. Now my teeth are a little crooked again.
