User blog:3primetime3/Color Bomb vs Colour Bomb

The title says it all. Which one should it be? This is a huge inconsistency.

Problems:
 * Half of the pages say # Colors
 * Half of the pages say # Colours.
 * A quarter of the pages say Colour Bomb.
 * 3/4 of the pages say Color Bomb.
 * All of the categories say #-colour levels.
 * The badge says Colour Bomb! for making 500 edits on articles.

I temporarily renamed the Color Bomb page to Colour Bomb and the booster to Colour Bomb (booster).

What is the solution?
