Fyrinnae Electric Stardust is a slightly warm-toned, light green with a frost finish. It is a permanent eyeshadow that retails for $6.80 and contains 0.1 oz.
Fyrinnae Electric Stardust Arcane Magic Eyeshadow ($6.80 for 0.10 oz.) is described as a "light, glowing, mint green sparkle." It's a light, pastel green with a subtle cool undertone and a frosted, sparkling finish. It is quite a bit darker and has a more frosted finish compared to Fyrinnae Jade Ghost, which I reviewed recently. Guerlain Coup de Foudre #3 is slightly gray in comparison but is close. Cinderella Cinderelly is nearly matte and is more cooler-toned. Make Up For Ever #34 is close in color, perhaps appearing darker because it has a satin finish.
Fyrinnae’s Arcane Magic Eyeshadows are specialized colours with a highlight that changes hue depending on how the light hits it (closer to or further from a light). Different light sources may show different shades, too (they do not show as well in sunlight as artifical light, and some may not appear to change at all). Please note that the Arcanes will probably look a little different in photos than in person because of the light-change effect.
