I organize by color, too, but if I have several from a line, I group them together, as well. I have all Xmas fabs together. I have most of my fabrics in those hanging closet shoe and sweater organizers, so larger cuts go in the sweater sections, and fq's and smaller cuts are in the shoe sections, but by color. I have been putting cuts of over 2 yards on empty bolts as I get them, on the top shelf of the closet standing up on end, and newer fabrics I am working with on bolts on a shelf in my sewing area. I have been buying multiple fabrics from the same lines for making purses lately, so I have them on the bolts grouped together.
