It occurred to me shortly after I finished my first Thalia that the pattern would work well as a two color shawl. After putting the finishing touches on the Mystery Shawl pattern, and looking for a new project to take on a little get away to Malibu, I treated myself to some vacation yarn - three skeins of Claudia Hand Painted Yarn Fingering.
The nice thing about fingering weight yarn in 50g hanks (think Koigu KPPPM & Claudia Hand Painted) is that with multi-colored shawls there is less waste. I was able to make this version of the shawl using two skeins of my MC and one skein of my CC. If I had used 100g hanks there would be more than half of the CC left over.
To make the two color version I alternated colors every two rows throughout the body, then switched to only the MC for the border and finally bound off using the CC. There are certainly other ways to make this a multi-colored shawl, like alternating yarns every 4 rows, or using three colors instead of two. If anyone decides to try, I'd love to see what you come up with.
Don't ask me what the two colors are, the ball bands are still tucked away in my luggage. Once I finish unpacking I'll put the color names up on the Ravelry project page.
ETA: According to the ball bands the colors are MC - Lipstick & CC - Mangled Tangled, although they look more like my photos than the colors on the Claudia Hand Painted website. The Mangled Tangled is a semi-solid deep, dark purple and the Lipstick is more coral than pink.
