On ClassicWB GAAE installation it asks you if you want the Alien Palette or an Earthlink Blue palette.
If you choose the Alien one... then you'll have the Green one or else the Blue.
If you like to change when installation if done... you can do this anytime.
Just head to
System --> Prefs --> PaletteThen from the right click menu head to
Project --> Open and double click the Palette drawer that you'll see.
Inside the drawer there are some palettes you might use like the Blue or Green or even Purple. The default palette is a classic MagicWB palette.
I guess you're set now
