Miku | Matisse acrylic paint

Lightfastness rating = although these pigments have not been tested we believe them to be supremely lightfast given there are examples of their use within the community that have been dated back far further than art history itself. We also believe they are lightfast due to their chemical make-up - ie iron oxides and so would expect them to perform as well as any other similar pigment ie an ASTM 1
