i agree with what coils said about the dust...not good.
i personally prefer all natural...no colors, no dyes & no scents for my household.
i saw colored mulch when i was shopping for cedar bedding for my snake terrarium & i was like "colored mulch, really? why? wont that dye leech into the ground & cause problems with the plants its around?" [shakes head]
one thing i know for sure...you cant alwaystrust the packagings "claims".
