I really like the color red. It makes things stand out and you can't help but look at them.
Like this building I saw in Sofia, Bulgaria:
I don't think this building was a governmental building or anything like that, it was just painted the color red and in contrast with the normal color of the road (grey/black) it just pops, . I think more things should be brightly colored like this. :) And no, the walls in my house are just a plain white, not multicolored...however, we do have a bright red table as a desk! :)
