Dior Cool Neutrals (002) is a permanent eye palette that retails for $49.00 and contains 0.35 oz.
Dior Cool Neutrals (002) Backstage Eye Palette ($49.00 for 0.35 oz.) includes an eyeshadow primer and eight, powder eyeshadows in a mix of soft pinks and muted mauves. It's the "cooler" toned palette (I bet the name gave that away), and given that there aren't that many readily available cool-toned palettes, I can see it working well enough for the right person. It was better than the Warm Neutrals (001) variation, as it wasn't quite as powdery and was more consistent in performance.
I don't normally test eyeshadow with primer and have that reflected in the ratings not unless it's explicitly stated to the contrary (e.g. the brand doesn't make a claim that the eyeshadows are long-wearing and pigmented on their own). I do regularly test new formulations with and without primer so that I can pass on any insights to readers as a separate note (but it wouldn't be reflected in the ratings).
I applied each shade with and without primer so that you'll be able to see how they perform over Dior's primer. Note: the very point of primer is to extend the wear of the eyeshadows, my rule of thumb (based on past average wear times of eye primers as Dior didn't specify the length of wear beyond "long-wearing") is 12 hours (this would equal a 10/10 score). The primer in this was decent but not particularly great, and I found it added texture to my lid.
Per the brand, it's supposed to be an "all-in-one" palette that includes a primer that "provides long-lasting hold ... [and] intensifies the effect of the color that will be applied over it." The eyeshadows are supposed to be "buildable" (and designed to be "long-wearing yet richly pigmented") and "blend beautifully" and "can be used as either eyeshadow or liner." Without the primer, this palette would barely be worth reviewing; the formulation of the eyeshadows is very soft but powdery with some shades that were drier and on the dusty side.
The lighter shimmers I had to use with a dampened brush to get evenness and adhesion as the textures were dry and prone to sheering out with a moderate amount of fallout (even over the included primer) and left behind either no shimmer or little pigment. The mattes were better with a more blendable texture and more consistently pigmented, and they applied better over the primer.
The Backstage Eye Palette is the Dior makeup artist’s secret weapon to create an array of pro eye looks, from natural to bold. Inspired by the energy backstage at runway shows, this palette includes shades that suit all skin tones. This all-in-one eye palette has everything you need to prime, shade, and highlight for runway-ready eyes. The easily-blendable powders come in eight shades and two finishes for an array of customizable eye looks. It includes an eye primer that reinforces shadow hold and enhances the look of pigment. All eight shades are designed to blend beautifully, and can be used as either eyeshadow or liner.
