MAC Trusted Instinct #5 is a moderately cool-toned, dark taupe with a frost finish. It is a limited edition eyeshadow.
Trusted Instinct #5 is a blackened taupe with hints of purple and brown that has a more frosted, slightly sparkly, finish. It is fairly sparkly, though a lot of the sparkle doesn't translate onto the lid, but there is some fall out over time. It had semi-sheer coverage applied dry and opaque pigmentation applied damp.
