To make things easier since the avatar builder is down, here are links to some of the item guides and whose color schemes I think they match:
Ghastly Purple and
Melty Kiss - Melody Nocturna, Shadeaux D Gloom
CMYK - Atomica Servo, Astrid Fantasy, Peggy Springwell
Alleycat - Demona
Checkmate and
Purple/Blue- Roswell Gray, Estrella Espacio
Candygloss and
Bubblegum - Cassandra
Cherie and
Olive - Tori Underbridge and Harry Herne
Schoolboy - Dashner Hawke and Falconnie Hawke
Durem (also search the term Obsidian) - Gryff and Glen da West
Barton and
Denim - Lin McGearloch
These are the ones that most immediately jumped out at me, at least. There's more color scheme guides here:
