Pigment Red 190 (C.I. 71140), also called Vat Red 29, is a synthetic organic compound that is used both as a pigment and as a vat dye. Although structurally a derivative of perylene, it is produced from acenaphthene.[1]

It is usually applied for cotton fabric, jig dyeing, PVA and silk dyeing, still may processed into organic pigment.
