Yesterday I wanted to try a purple and blue look. I had seen a great picture online with a gorgeous combination and tried to recreate it from memory. I think this would have worked even with matte shadows, but I like how it came out! I believe the key to making the colours look nice is to have them be the same darkness, so they blend together easily.
Sugarpill Starling (warm medium blue with a lot of matching sparkle)
Evil Shades Chusi (warm purple with some shimmer)
