There are many theories and tales about the meaning behind the lightsaber colors onscreen in Star Wars. Eight different colored lightsabers have appeared in live-action films or series. However, viewers have not gotten explicit details regarding the construction, color, or Fore-connection between the wielder and the color. As far as the science of hilt construction and crystal mechanics goes, this lack of specificity may be due to the difficulty in reconciling the fiction of lasers being used as swords.
