Guerlain #04 is a very warm-toned, light-medium copper with a semi-matte finish. It is a permanent lipstick that retails for $33.00 and contains 0.12 oz.
Guerlain #04 Rouge G de Guerlain Matte Lip Color ($33.00 for 0.12 oz.) is a muted, medium-dark coppery brown with warm undertones and a satin finish. It had semi-opaque pigmentation in a single layer, which applied evenly and smoothly across my lips without emphasizing my lip texture. It was one of the more flattering shades to wear within the range, which is a sad state of affairs given it's part of the Rouge G family. The lipstick felt lightweight, thin but not clingy, and was comfortable to apply and to wear, though I wouldn't describe it as hydrating during the four hours it stayed on for.
