Review (4/5): Really like this, some colors are better than others
I really like these!
I have very dark brown hair, almost black.
The best ones were purple and blue, they showed up quite well on my hair (I passed over the same area a few times).
The yellow and hot pin was also moderately opaque.
The green and pastel pink did not show up on my dark hair. Overall I would buy the purple and blue color again.
