Tom Ford Beauty Spice is a very warm-toned, medium-dark brown with a metallic finish. It is a permanent eyeshadow that retails for $45.00 and contains 0.17 oz.
Spice is a medium-dark, copper bronze with warm, red undertones and a pearly sheen. It was intensely pigmented; a little goes quite a way, so I highly recommend using less than you think and then building if you end up needing more. If you want a sheerer wash of color, I would apply to the center of the area with a tiny amount, then blend and diffuse to a sheerer layer. I think it is easy to wear it totally opaque or sheer it out, but as it is quite pigmented, it is easier to wear it opaque. On me, it wears for nine and a half hours before creasing (actually, it wore a little longer than the last time I tested it--by a half hour). MAC Bao Bao’s Jewels #3 (LE) is powder, lighter. ColourPop Deluxe (P, $5.00) is less shimmery. ColourPop On the Rocks (P, $5.00) is less red-toned. Kat Von D Depeche (LE) is a powder. MAC Mortal #4 (LE) is lighter, powder. Make Up For Ever ME654 Cauldron (P, $21.00) is a powder. Make Up For Ever I662 Amber Brown (P, $21.00) is lighter, powder. Make Up For Ever I634 Praline (P, $21.00) is less shimmery, powder. Urban Decay Smog (P, $18.00) is a powder. Urban Decay Baked (P, $18.00) is a powder. Inglot #405 (P, $6.00) is a powder. See comparison swatches / compare dupes side-by-side.
