I wonder if it could be about someone (Ayu) falling in love. The green represents her as happy and almost carefree. The black could be an attempt to be indifferent to any new feelings by being confident and cool. The color black could represent hiding feelings (the color black absorbs all light). The white is represents finally giving in to love and the shy, happy feelings one may feel at the beginning of a romance. I think the white not only represents purity, but also the releasing of those hidden feelings (as white reflects all light). Red is the consumation of that love (I think Love Appears put it really well). I think the color red represents passion.

Maybe the "tin man" looking at the spinny-thing (for lack of a better word) is symbolic of her significant other reflecting on the different sides he has seen of her, while the Ayu lying in the rain is the not only a combination of the four Ayus, but the end result of a path in which all four sides were shown; and she is completely comfortable and happy with herself now. Each of the four colors of the four Ayus is present in some form or another in her outfit at the end, even white and black. If you were painting a picture of Ayu in the rain, you would need to mix white with green and white with red to get the color of her shirt and shoes respectively, and black and green would get the color of her pants.

Okay, bedtime now
