MAC Deep Truth is a very cool-toned, medium-dark blue with a frost finish. It is a discontinued eyeshadow that retails for $17.00 and contains 0.05 oz.
Deep Truth is described as a "true dark blue [with a Frost finish]." It's a medium-dark, brightened blue with a frosted finish. It had good color payoff with a fairly soft texture, but it was stiffer and thinner compared to the permanent version I have. It wore well for eight hours and was easier to use than I expected, based on the texture. See comparison swatches / view dupes.
