Blue is
tres coo'.
And according to
feng shui of the website kind blue and white is just right. Winds and rivers of prosperity and stuff, you know.
The red conjures the bad karma of a setting sun. Do you want the sun of fortune to set on this site? DO YOU? And cast it into eternal night, sparse posting, incorrigible n00bs, and inactivitiness?!
Gray totally represents earth and that evokes the energy
malo of rocks and dams and constipation, which leads to suffering, which comes from hate, which emerges from anger, which is the child of fear, and y'all know that FEAR IS THE PATH TO THE DARK SIDE. Well, er, back to the rocks and dams part: Gray is damming (lul) the site to bad feng shui! Damning, I say!
And the green, well, forget what feng shui says, but I like the green. It's minty! And going green is totally trendy nowadays anyway.
