"Intensely pigmented" eyeshadows unfortunately do not match at all. One thinks they added pigment just by looking at them. Colorless powder for a lot of money, I recommend no one to waste their money on!
Thanks for the reply! Unfortunately, I've tried all of this as it felt sad to throw 300 kr in the trash, but primers (from different brands, both budget and more expensive) made the shadow patchy when applied, and trying to blend it continued to lead to it just disappearing. When I built it up with a brush (both dry and wet), the shadow blows away after a minute. Since it also doesn't seem to be that popular considering the number of reviews, my warmest recommendations are to consider stopping to stock this haha.
