MAC Cool Jazz Technakohl Liner ($16.00 for 0.012 oz.) is described as a "navy blue." It's a medium-dark, brightened navy blue with a satin finish. The consistency was slightly dry, fairly waxy, and prone to skipping. It had semi-sheer color coverage in a single pass but was buildable to mostly opaque color coverage. It started to smudge after six hours (looked blown out). 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.
