The holographic glitters reflect many colors while the white hexes are a solid white.
When I got this, I approached it as any other top coat...apply it over white and black and see what happens. I used Fingerpaints Papier Mache' and Cult Nails Nevermore. Each finger has just one coat of Seche Collage Overlay and I was able to manipulate a piece or two as I wished.
And THAT's when I realized there were white hex glitter pieces in this mix. Look at the tip of my index finger and you'll see two white hexes...if you squint and stare long enough. For this reason, I wouldn't recommend wearing it over white.
Oh heck, it's not bad. I can see the white pieces with my naked eye, but still white on white probably isn't the best way to display all the functions of the Collage Overlay.
Then I did a colorful swatch wheel and swatched the Seche Collage Overlay on top. You really have to see this in person; it's so much more three dimensional than a flat picture. The holographic qualities of the glitters make the polish flash rainbows and brightness as you roll the fingers around. At any rate, I'm going to do a full manicure and wear it over the color at the top, number 16, Layla Softouch Effects 05, a two-toned rose with a hint of gold.
It really looks great over all the colors I tried.
How will you wear yours? Any color combinations that you have in mind?
