Below are swatches of Nabi 3D Hologram #24 Purple. It is a dark magenta/purple with a scattered holographic effect. I used one coat of Instant Artificials and two coats of #24 Purple. I did not use a top coat because it does dull the overall effect to the point that it is no longer holographic.
My camera pulled a little more magenta on these photos than the color is in real life. It is a tad more purple than in my photos.
