My opinion has not changed much from release:
1. Blue
2. Yellow
3. White
4. Black
5. Green
6. Red
7. Orange
8. Indigo
9. Violet
Violet to me just sounds too much like their normal sound to me. With the others I really feel like they stretched things out.
BTW, is it just me or does anyone else find the only way they can listen to the EPs is from Black to White? For some reason listening to one Color by itself to me feels like coming into the middle of an album, it's weird.
