MDM Flow Lipstick in Vamp While many of the dark lipstick shades on this list fall on the warmer side of the colour spectrum, MDM Flow Lipstick in Vamp (£15) is a blue-based dark colour that could best be described as a moody magenta. And because it's super pigmented, it's a colour that works on any complexion, from the fairest to the deepest. Image Source: mdmflow.com MDM Flow Lipstick in Vamp £15 from mdmflow.com Buy Now
