In my opinion out of playing hundreds of games, first player(s) are having an advantage of getting best position and having the best chance to use his/her colour in the best way.
Example:
In a game with 4 players if you are 4th player you sometimes get no chance either to howl or build a den cause your colour is out of range to do so. You are forced to move first and lose a half turn additional to the fact that the other players had the chance to howl/build den.
My suggestion to improve this, would be, that 4th player get the chance to choose colour first, than 3rd player etc.
