I have a holiday quad from back in 2011, with Phloof, quarry, brun and dance in the dark which is a deep brown color.
Quarry looks amazing with brun =) - However they are both mattes and I like to mix shimmer with mattes, so I like phloof as an accent color - its like a frosty warm white shade, I feel like it balances the cool-ness of quarry and brun.
- for reference Im an NC20 with dark hair.
