I did think about it, but I don't think it's too bad -- the site is plastered with "unofficially" and the disclaimer to prevent that.

I love how minimal HN is and I don't think I've ever seen orange work this well on a site in my life to be honest, so I wanted to pay a little homage and also have people feel at home.

I'll definitely consider changing the theme, and I've already added a disclaimer.
