Chanel Architectonic #2 is a very cool-toned, dark gray with a frost finish. It is a limited edition eyeshadow.
Architectonic #2 is a deep gray with a bluish tone and a soft pearl shimmer. It had good pigmentation, though not fully opaque, with a drier, thin texture that had quite a bit of kickup in the pan. This shade applied decently to bare skin but turned noticeably patchy when I started to blend it out in the crease. I saw signs of fading after seven hours of wear.
