This is not a detailed review and comparison, just a quick post with a few pictures.
Convoitise looks like a yellow shimmery gold in the pot. It has the same light and bouncy textures as the other Illusion d'Ombres, but without as much glitter or sparkle.
On the skin, Convoitise is a light gold. There are shimmer particles, but this mostly has a smooth finish.
Convoitise might be my favorite Illusion d'Ombre yet. It is less sparkly than the others I own, (swatches here) making it great for an everyday look. The gold color is very brightening, and adds a polished glow to my lids.
