Hi guys, this is my first post here and I was wondering, what are some card color changes that can be done surrounded under any conditions besides the Classic and the Edernase color changes?

Pretty well any of the color changes that work from stealing a card into palm can work surrounded. Others like the snap change work great too. Just have to hold the card more down or block with your body if anyone behind.
I very often work the streets surrounded and color changes are how I gather a crowd. They're great. Easy to understand, visual....just need some snappy patter to add a bit of humor and you have a killer routine.
Stuff like the Bertram color change can be angle sensitive.
Other changes that work from a thumb clip for example can be done surrounded if you do it in front of your body thereby blocking.
There's a great digital book on Lybrary.com called 'The Color Change' that lists over a hundred changes. Most can be done surrounded if you pay close attention to your angles.

The duck change and shapeshifter can generally be done surrounded.
