To dip dye or not to dip dye

The dip dye hair trend is still going strong and I'm seriously concidering jumping on the wagon. Only problem is that my hair is dyed black so I can't bleach it without ruining it, so I'm not sure if I should take the risk. As it is now, I have red dyed bangs so if I were to dip dye my tips, I'd need the color to correspond with my bangs. What color would work with everything? I'm still not sure if I should do this but I do enjoy seeing the bright hair colors on catwalks and fashionistas everywhere.
