Does leaving a bath bomb out too long also affect the color? I made the mistake of waiting to use my LoM bath bomb until a special occasion (read: the night of the inauguration, when I felt I was bathing in America's blood) and it didn't fizz up a lot. In fact, it took forever to fizz out. That's fine and dandy, since I've read it can happen, but the color wasn't as deep as I've read about. It was more of a purplish-red than blood-colored.

Regardless, I smelled sooooo good and felt very sinister in my bloodbath. :)
