Several paint colors in this brand have a fairly poor lightfastness rating. The poor ratings are mildly surprising in light of the brand literature which specifically notes permanence. At the time of this writing, this sub-brand has multiple paints containing pigments such as PY100, which are rarely used in artists oils. PY100 in particular is known to fade and has a lower lightfastness rating than Alizarin Crimson. This color also contains synthetic Alizarin Crimson. Given the brand’s heavy reliance on organic (meaning carbon-containing) colors, doing one’s own lightfastness tests is especially advised.
