My favorite color is yellow. Not to wear - I look dead-ish in yellow, but I enjoy my surroundings to have yellow. My walls in my home, with the exception of two rooms, are yellow (egg yolk-ish).
If it tells you anything about me, I suppose it would indicate that I prefer cheerful surroundings that bring light to the dark corners.
Yellow is a very friendly color, forgiving and actually, goes with just about every other color.
