Lilac Reef Curassow is a medium-opaque, pale lilac with an iridescent effect. Unforgettable Oriole is a delicate, metallic white gold, which makes a 'perfect highlighting eyeshadow'. Honestly, it's too pigmented to work on my browbones, but instead it might work nicely as a cheek highlighter. As usual the eyeshadows have a buttery texture and colours can be built up in layers, as RBR products tend to be rather medium-opaque yet easy to blend.
With RBR recently launching in the US and the palette system offering a nice opportunity to get into the brand, I have high hopes they'll receive the credit they deserve. The only downside - once again - is the price. The duo keeper retails for ~19$ whereas the pan eyeshadows cost ~26$, a total of 71$ for a complete set yet a must-have for those preferring neutral colours with a shimmery twist over bold pinks and yellows.
