I will attach some photos after I get my daughter to pose, but these chalks go on so nice and easy. The combs are perfect for my daughter's extremely long hair, they show up beautifully and colorful enough after just a couple strokes in her hair. She does have light hair, not sure how they may show on dark hair but the colors are bright. I think it would show up well, you would just have to do more strokes to get, or until you get the color bright enough to show up on darker hair. The best part of these chalks is that they are so easily applied because of the combs they come in, makes it so simple to apply that she can do it herself. Very fun, bright colors that have a very easy, and neat application process, I highly recommend them.
