Out of the tube this is a smashing, electric purple. However, when dried, Cobalt Violet Light is subject to some notable yellowing over time (probably due to the choice of binding oils, or possibly a varnish). For this version, the effects can be observed both on the painted areas of the tubes themselves as they age, as well as the color charts which are subject to additional dark yellowing. If vibrancy needs to be retained dried, one idea is to try this pigment in other binding oils such as Blockx or Williamsburg’s safflower oil version. However there may be other issues to be aware of with safflower and poppyseed oil as binders. It is agreed that linseed oil, which is subject in general to greater yellowing, also is the favored candidate for creating stronger paint films. In any media this pigment is not a strong tinter. However its relative lightfastness and high chroma in this part of the spectrum makes it a desirable addition to the palette. Overall we love Cobalt Violet Light as a pigment, and out of the tube this is as bright and brilliant as any we have seen. Update: Unfortunately Cobalt Violet Light PV14 (Light) has recently been discontinued.
