gtx ltd seat cover

im in the process of picking up a new seat cover from the forum store.. however.. im having the hardest time trying to figure out the color which would best match my "blue" on my gtx limited.  does anyone know exactly what this color is called??  I would like to contact the company to see if they carry anything similar to this color.  if not I might have to stay with the old, faded cover for a while.
