Deep Truth is a dark blue shade that is matte in consistency with a small hint of glitter. It is beautiful on brown eyes and even blue eyes, because it is a darker shade. I like to use this one sparingly and in more striking areas of the eyes (crease and outer corner, for example). It is harder to blend than most other MAC eyeshadows, but with patience and persistence, eventually it blends out beautifully. I especially like the way Deep Truth looks with other purple shades.
