I am undecided on this as well. I make soap and b&b as well and the only thing I've been coloring is my soap. Lotions, creams, body glazes, I leave as is and rely on my labels for coloring. For scrubs, I add a little bit of jojoba beads for color. I want to add soy wax melts to my line and am deciding on whether I want to add color or not. While color catches attention, it can be subjective to the customer as well. Since I package the melts in clamshells, I will also have a label that will be eyecatching as well.
