UBBC in Personal Text Acting Up

Your problem description is a bit misleading since it says "use a color tag for just one word" when the actual problem stems from using multiple color tags

The [color=red]fire[/color] in my eyes, the [color=maroon]fury[/color] in my soul, the [color=lightblue]chill[/color] in my voice; [b]Will it lead us to victory?[/b]

You'll need to add the question mark (made oversized so you can easily spot) to the line that handles the color UBBC tag to make the regular expression less greedy. As it is now it looks for the last "[/color]" instead of the first it encounters.
