Description This chart was scanned immediately after coloring and in various increments over the past eight weeks, during which time the paper has been sitting in a south-facing window, though never in direct sunlight. I have combined the scans such that the first row of each color group is from the first scan (day 0) and the second is from the most recent (day 58).

This chart shows the amount of degradation that has occurred so far, but not the rate at which it has occurred. For instance, BV00 became pink after only a week and and has changed very little since then, while others like B29 have been changing at a steady rate the whole eight weeks. Interestingly, some colors haven't changed very much if at all.

Since color change is still occurring I will continue the test for at least another few months.

NOTE: I didn't adjust the colors after scanning like I did the original chart I posted so the pale colors wouldn't become washed out. The gray stripe on the right side is something new my scanner is doing... it might be time to get a new one.
