Described by MAC as a "warm copper", in the pan Bad Girl Gone Good looks fairly dark and orangey-brown like a bronzer. On my skin, it transforms into a medium dark peach with slight brown undertones. This is definitely a fall blush colour - it's dusky and earthy - not your usual bright pop of summer coral. It took me a long time to appreciate brown based shades of blush such as this one because I always thought brown based shades would look muddy against the skin. However, what makes brown based blush shades great is that they usually are very neutral, and therefore are great to pair with more dramatic eyes or lips.

It applies smoothly, blends well and is buildable. This would be a great colour to pick up for medium to dark skin tones. On lighter skins this could be a great contour/peachy bronzer shade. Despite my overwhelmingly large collection of blushes, I can't think of one I already own that is like this colour. Recommended!
