I started a fadetest in Maryland US on October 6, 2013. The inks being tested are: De Atramentis AubergineParker Quink Washable Blue (cartridge)Pilot Cartridge OEM with 78G Fine (presumably Pilot/Namiki Black)Diamine Ancient CopperDe Atramentis DianthusDe Atramentis Robert Louis Stevenson South Sea BlueLevenger Gemstone GreenNoodler's Turquoise EelNoodler's HabaneroPelikan 4001 Brilliant Black I re-scanned the page on October 19, and again on November 9. This was not a high amount of sunshine month; the days are getting shorter and the weather was wet or cloudy more than other times of the year. The test page is still in the window and will be re-scanned periodically. So far the Parker Blue is already mostly faded away, Dianthus is significantly faded, and both Robert Louis Stevenson and Gemstone Green have changed color. The others are either holding up or only slightly changed or faded so far. Following are the initial scans and these first two scans after exposure. You can click on them to see the original full size scan, or find them at my website.
