Well perhaps the corrilation of blue to house and red to minitaur(sp), is a Simple Phycological catch. Red Corilating with something bad, or a warning(sign), or blood, also red being a color that is usually connected to such emotions as anger, and Rage.
The Fact that "minitaur" is the word written in red may also have its own phycological hooks. a Minitaur being a feirce, scary deformation of the human figure....I does bring to mind some interesting images.
Now to the blue. Blue has all sorts of interesting Phycological hooks. First its a Color conneted to calm and tranquility, not to mention many shades of blue are used to represent two things that are the most vital things for life, those being; air and water.
House written in blue. Well lets just look at what a house usually symbolises. It is a form of protection, from both the elaments and the people on the outside. It is one of the few things that many people think is truly theirs. Its saposed to be a sanctuary.
thats pritty much what I got right now, well there is also the obvios opposition of red and blue and of there connection to other "realms" i.e. Hell and Heaven respectivly.

yeah i agree with whats being said. also, i believe, that the blue somehow triggers a likeliness to website hyperlinks. originally, most of the internet used those blue hyperlinks. i see it similar to the house because it has a multi-dimensional sense to it. like, 'this house will lead you somewhere else entirely' ...
