Midnight star - For me, dye release starts almost immediately. It was staining hands and paper towels 15 minutes in. And when I froze & thawed it, wow.

For me, with my ash brown virgin hair - Red Raj stains like crazy. I was so worried I'd end up a flaming red head, but 3 hours made me auburn - and I'm really dark ash blonde, technically. It's a gorgeous color but if I was going for a lighter red, I'd have shot way past that. Maybe I didn't need it on so long? Either way, I love it. It looks completely natural indoors - in the sun, that glow gives me away!
