I'm not a Falefo shill (lol), but I think you probably won't have many opportunities to use colors like these, so I thought I'd report on them. The Falefo polarized colors came in a set of six. I've made samples of colors other than the ones I used this time to show you what the finish will be like, so I'll report on them. They're also available online, so if you're interested, please take a look there as well.
There seems to be a naming convention, and they're in the format of main color/polarized color. Below, the samples were sprayed directly onto a black plastic spoon. This time it's this "Magic Dust" set.
① Violet/O
