The White Wizard
I like it because it succeds in tuning down the Colossus, making it less powerful. Initially I also suggested it as a wealth wonder.
I dislike it because, after deeper consideration, I could see the Colossus acting only in three ways, which I already told:
1) as a gigantic monument, which fascinates foreigners and maybe can give a gold bonus, although in Civ monument provides only culture;
2) as a lighthouse, which gives food per water tiles;
3) and as an entrance for an harbor / yard (ships passed underneath its legs to enter the bay).
Combining these 3 roles, my shot was to give it +1 hammer per water tile and war weariness for your enemies (less than Zeus, so it's not OP).
The Colossus was never used as an entrance to a harbor, that's a myth. However, as a symbol of power, it would enable coastal traders to travel farther unmolested (Who would want to attack merchants from a nation with the power of the Colossus behind them?) and earn them greater trading wealth.
