As far as LEGO bricks go, I am just a bit OCD (or more than just a bit). I’ve been spending my evenings going over my collection, parting out sets and parting some of my MOCs. This is what happened while sorting last night. There’s the most popular/common brick colours currently used by LEGO. My favourite colours (at the moment) are the bright light yellow, sand green, light aqua and lavender.
