I love Violet Pigment, too! I'm thinking I should have probably got that instead of Tan. I do still have some sample left of Violet, though.
My other favs are MAC Digit (really useful pale lavender that's good to pair with other purples), MAC Creme de Violet (really eye-catching and rich and looks amazing blended with dark purple), MAC Parfait Amour (pastelly bright blue-toned purple. Another eye-catching shade), MAC Nocturnelle (nice rich deep red-toned purple), Stila Cassis (my HG purple crease colour of the moment. Dark shimmery blue-toned purple), Urban Decay Asphyxia (really pretty light bright lavender with blue shimmer), and MAC Idol Eyes (haven't worn this much but I vow to wear it more because it's a really pretty and unique lid shade - pale greyish lavender with pale gold shimmer/glitter).
