Primary #4 (Vol. 1) is a bright, medium yellow with warm, orange undertones and a lightly glossy finish. The texture was more slippery compared to other shades in the palette, so the color was harder to apply and keep in place--there was visible streaking, and the moment I pressed my lips together, it looked even worse as the color moved around. There was some color that pulled into lip lines, too. This shade wore well for four and a half hours and was neither drying nor hydrating.
