Sight Without Sight

Feel an object. Build it in your mind by touching it with your hand. Craft mentally its edges and texture, and all its dimensions. Now, imagine being able to gather this data without touching anything at all, simply being in its presence sufficing. This is Sight, and its an ability that also allows one to gather data from an object touching it cannot. This data is Color. Color is nothing beyond what you already know about objects, only an additional feature applied to them. It is the quality that allows two objects that are exactly the same, two objects of identical size, weight, and texture, to differ, and be separately recognized.
