Guerlain Rose Barbare #4 is a moderately warm-toned, dark purple with a frost finish. It is a discontinued eyeshadow.
Rose Barbare #4 is a dark, plummy purple with subtle, warmer brown undertones and a satin finish. The consistency was so dry and thin, which made it a real pain to blend out as it turned patchy. I thought it would be improved over primer, but it applied just as badly. It had good pigmentation, but the texture was a total miss. It wore well for five and a half hours before creasing.
These shades feature matte, satin, and metallic finishes and are enriched with light pigments, reflecting light to make the eyes seem more open and brighter.
