I have my closet organized by type, like all skirts together, all pants, all dresses, all tops. Only pants and skirts are actually color-coded. I also put multiple garments on the same hanger sometimes to conserve space, like skirts, some pants, blouses, and camisoles can all share. For picking out what to wear, I usually pick one item (usually a dress, top, necklace, or purse) I really want to wear and then just go from there. Most tops will go with either black, brown, khaki, or denim ( or all of them).
