I have been a long-time Viseart fan and I own most of the palettes (minus a couple of the most recent) so I held off on the Theory Palettes when they released thinking I'd see too much overlap in my particular collection. Recently I decided to give two a try simply because of their compact portability and I am so glad I did! Not only am I not seeing total overlap, but I reach for them all the time. I love that most of the large Viseart palettes are organized by undertone and/or finish because I don't often purchase palettes assembled to create a specific look, but the Theory palette doesn't give me that restricted feeling. I can use each to create one look or I can seamlessly blend shades from the Theory palettes into looks created using multiple palettes. Just great all around (shades, texture, performance), you won't be disappointed! Also, I travel frequently and between its slim size and no-plastic packaging (I get so tired of worrying about cracking) it's perfection on the go.
