Sydney Grace Pumpkin Spice Latte Loose Highlighter ($8.00 for 0.25 oz.) is a light orange with strong, warm undertones and a pearly sheen. It had opaque color coverage in a single layer, though the loose format makes it a little harder to tell how pigmented is pigmented as readily as with a pressed formula!
I didn't feel like I had to be extra careful to get the smallest amount for coverage, but I didn't need more than a light tap of a highlighting brush into it. The consistency was silky, finely-milled, and blendable, which made it easy to apply and diffuse. It wore well for eight and a half hours before fading visibly.
