Okay, at the end of the opening credits, you have to look at Irma, (she's the one with the brown hair, in the corner.) Look at her shirt color in her "Guardian" form, Her shirt is purple and her skirt is green. However, in the episodes Irma's shirt is green and her skirt is purple, which is how her outfit is suppossed to be colored, according to the book and the rest of the series.
