Cirque Magnum Opus was released as part of the Alchemy Collection last autumn if I am not mistaken. Magnum Opus is a wonderful mid-toned grey with a very fine holo rainbow. It sparks beautifully in the sun and seems to float on the surface of the nail. On top Magnum Opus fine holo adds an incredible depth to the grey base color. Indoors a soft lilac shine radiated from my nails and the slightest tinge of a holo rainbow was still visible.
Final thoughts: What a perfect grey holo - I just love those mid toned greys, they have a minimalistic coolness about them that keeps me captivated, throw in some holo and it morphs into sci-fi-tasticness!
I look forward to reading your comments - thanks for passing by!!!
