I use a chest of drawers for my thread cones and clear plastic bobbin holders with lids for my bobbins. I label the bobbin holders by type of thread. It's easy to see the colors when I pull out a drawer and it's also easy to see if I have any prewound bobbins with the clear holders. I try not to wind more bobbins than I need and if I have 2 cones of the same color this makes it easy. (I have a stand alone bobbin winder). This works for me.
