Why did Kaoru's hair color change?


In the very start of the first episode, Kaoru had Dark blue hair. But after
that, her hair color changed to blonde. Why did Kaoru dye her hair? Does it
mean something like a start of a new chapter of her life? What is the
significance of this in the story?

When they got married, Kaoru's hair was black. After a while, Kaoru dyed her
hair blonde.

In the [web comic version](http://ilovecool.web.fc2.com/vippperdays/top.html),
[chapter 6](http://ilovecool.web.fc2.com/vippperdays/6/6.html) has the story
explaining the reason why Kaoru dyed her hair blonde:

  * 2nd frame: Hajime: Uwah~~~ Sadako-tan so moe~~~ I want to lick you all over~~~
  * 3rd frame: (Kaoru is angry)
  * 4th frame: Hajime: Oh? You dyed your hair? (Kaoru is sulking)

I think, Kaoru did a (light) cosplay of Sadako to get Hajime's attention, but
he called her Sadako instead of Kaoru, so she got angry and dyed her hair
blonde.
