I have completed a 90-day light fast test of NuPastels. I placed the chart in full sun from January 16 through April 15. Note that this is not a scientific test, but simply a test for my own use and verification of which colors held, which faded, and how much fade was noticeable.
For my observations I used a number system 0 - 5
0 - no change
1 - slight change in value
2 - significant change in value
3 - slight change in hue and value
4 - significant change in hue and value
5 - complete fade
If you contact me by e-mail, I can send you a complete spreadsheet of my observations.
