I am absolutely in LOVE with these holographic nails by Lynn! She had some on in a stiletto shape and I asked her are those like chrome/hologram nails? She said they are holographic and it's gel. I was a little hesitant worried it was out of my comfort zone, but I trust Lynn and her judgement so I said, "Go for it!" And I am so glad I did! You can pick the base color, I picked pink, and then the holographic powder/gel went over it. It was like magic! AHH-MaZing! By far the coolest technique I have seen in nail art. So, basically if you wanted more blue undertones you would pick a blue base, more purple undertones-pick purple/lavender. The darker the base color the more intense the holographic effect. I wanted something not too intense and went for a warm pink and it turned out great. I took pictures with a yellow and black background to hopefully show how the color reflects on the surface. If you want to try something new and talk about a showstopper-you have to give these holographic nails a try. Love it and thank you Lynn for having me step out of my comfort zone and try something new!
