Okay.
Got these for my daughter. She has light/medium brown hair with natural blonde highlights. It took a lot of chalk to even begin to show on her hair, and even then it was subtle. We did the pink on her. I used the purple on my bleached blonde hair, and it definitely showed up better, but looked more like a wine red, or burgundy. There's no way the picture in the post of the girl with purple and blue hair is real. So far, the color is not very vibrant.
