There has been a lot of discussion recently about Graphitints and whether they are lightfast. I was aware that some of them are very fugitive but it seems some of the ones that appear lightfast on the chart provided by Derwent, might in fact fade rather quickly. I use the graphitints dry and haven't had any problems so wonder if the addition of water causes them to fade faster.
As I was worried that my squirrel might fade I have changed the indigo graphitint for an indigo prismacolor, and the cool brown graphitint for a brown coloursoft. I also went over the entire squirrel to ensure it wouldn't fade in the near future.
