Brunette covers more ground than any other family here. Cocoa and Espresso are solid, believable browns that stay consistent from root to end. Bronzed Caramel and Toffee add a natural shadow root and softer ribbons through the mid-lengths, so the colour shifts the way lived-in hair does.
Choose a solid shade if you want colour that stays even and is easier to match to your own regrowth. Choose a balayage if you want dimension without having to maintain it. Bronzed Caramel keeps a brunette base throughout; Toffee sits closer to bronde and reads lighter around the face.
