For all of you wondering about lights, mediums and darks. I was introduced to this way of checking your hues to determine if a fabric plays well with the scheme you are attempting. You can line them up in the order in which your eyes perceives them, take a photo, then edit the photo to show the fabrics in grayscale. The color value of each fabric is really easy to see this way. Now you can choose a light, medium, and dark relatively easily.
