This covered dark hair, light hair... every color hair it was used on, with very little effort and very little spray. VERY nice.
Word of warning, however - though it was far less dust than the pink color, there was a little blue dust left in its wake. Nasty as it sounds, we were blowing blue snot for about 3 hours after using this indoors. I would recommend a vent fan running, or a dust mask while using this product, especially if you have sensitive lungs.
Still - far better dust-wise than the pink version of this brand of color spray, and AMAZING, breathtaking color.
