Hello~! I got a question last time how I made the vibrant yellow eyeshadow.. So thought I'd make a little post. Usually I use Coastal Scents 88 make up palette which colors are really vibrant. I usually use an eyeshadow primer for longer lasting makeup.. But it's also excellent for creating vibrant colors, especially for cheap eyeshadows as RIMMEL London which colors doesn't really show up unless you use a primer (as seen on the picture). Unfortunately, eyeshadow primers are not that common in Denmark, but I found out that GOSH actually made one, and it's cheap! I'm not a big fan of GOSH's since I'm allergic to their stuff.. But it works very well, and that's basically the one I'm using.
I recommend to pat the color on with your finger actually after putting on the primer. It gives the best results if you want the color to be vibrant.
So good luck and go color crazy! I do! ( ̄▽ ̄)ノ
