MAC Bishop Blue Technakohl Liner ($16.00 for 0.012 oz.) is described as a "blue-purple." It's a muted, dark purple with a hint of blue and a soft, pearly shimmer. It was sheer, dry, and very waxy, which gave it--at most--semi-sheer pigmentation and a faded quality to it at that. For me, this shade had smudged after six hours of wear. See comparison swatches / view dupes.
The liner’s enduring formula features a unique combination of plant-derived waxes, providing a soft, comfortable feel, while staying smudge-resistant for up to eight hours. Whatever your style, get ready to line it up.
