As promised, here's a comparison of Freya's Cats with my other scattered blue holos.
First of all, PLEASE ignore the labels on this first image. I don't know why I was such an idiot, but I deleted the photos off of my camera before realizing my stupidity. I copied and pasted my labels onto different fingers and forgot to change them before saving the image.
The polish are: (L to R) LA Girl Brilliant Blue, piCture pOlish Freya's Cats, piCture pOlish Cosmos, and piCture pOlish Freya's Cats (2 coats of Cosmos and Brilliant Blue, 3 coats of Freya's Cats).
No dupes here, although differences are less subtle in person. Cosmos is the darkest of the bunch, and slightly more teal. Brilliant Blue has larger scattered holographic particles than both of the piCture pOlishes and is darker than Freya's Cats.
Conclusion: piCture pOlish Freya's Cats is a pretty unique scattered blue holo! I can't wait to compare it to the new Zoya Dream!
