ColourPop Gold Rush Metallic Liquid Liner ($9.00 for 0.28 oz.) is a light-medium gold with moderate, warm undertones and a glittering, metallic finish. It had semi-sheer coverage in a single layer, and while it wasn't opaque, it had a bit more shine/shimmer that made it seem more pigmented at a glance (especially when viewed on the lash line from a normal viewing distance vs. close-up). The texture was more watery, so it seemed a little more fluid than ideal, and it would work better applied over a more opaque, solid matte eyeliner to add a glittering effect. It lasted well for nine hours but had a couple of glitter flakes after that.
